What's The Best Spark Plug For The Q45

[mzarkowsky]

From time to time I've seen people in this forum talk about the NGK Platinum plug as "the" plug to use. Is this the case? How about the Bosch +4 Platinum that seems to get rave reviews in the rest of the automotive world?

Three words - Do a search.

You will never ask again about Bosch plugs once you do.

Guaranteed.

By the way, to which electrode of the +4 does it fire? You know it will only be one since there is only one shortest path for the spark to follow.

Can I get an A-MEN!

[Q451990]

Before I even opened this thread I knew the second or third post down would be Brian saying "do a search!"

In any case - do a search for the long answer, or just take the short answer - No Bosch in your Q and order the factory plugs.

Use only NGK type spark plugs.

Use p/n PFR5B-11. You can get them from Joe, or you can email yoshi sakura ([email protected]) and see if he still has them. he sold me a set of 8 for $47.... UNBEATABLE price..

Id like to see Brian's first post in a thread NOT contain the words "do a search"

[TorQue45]

What is the difference between PFR5B-11 vs PFR5G-11?I just replaced my plugs with PFR5G-11. Is that going to give problem?

[HeavyDuty]

The B & the G are the exact same plug in diameter, reach, heat range, both platinum, etc. Interchangeable with the exception that the B is a proprietary design specified by Nissan/Infiniti and is architecturally the same plug with minor fire-in changes like perhaps, diameter of the platinum biscuit, shape of the electrode, etc.

Either should work, but the B must stand for "Blessed"

You should have no problems with the G, but I'd run B's just becuase.

I am certain as soon as the FAQ for newbies advises this, it will no longer be necessary. I have anticipated that day for some time now.

It should be SOP for anyone new to any forum to at least research a topic on that forum if they do not bother to read the previous posts before asking a question. There is not too much flotsam here, so reading the previous posts is not that daunting.

I searched the archives for almost two hours, to find nothing. Sometimes a simple answer, isn't that hard.

One search in Infinti Articles under Bosch: http://www.nissaninfiniticlub....Bosch

Two pages in Infinti General.

Three pages in Infiniti Mechanic (when will this be changed to Infiniti Technician?) including this relevant one:

http://www.nissaninfiniticlub....Bosch

Now that wasn't that difficult, was it? Was it the clicking?

Like someone before me said, "The problem with you kids is you missed the sixties." Evidently a lot of English classes in Junior and Senior High School, also. :pface __________________Brian1995 Q45 & Q45t & 2000 Q45

Calm down, no need for anything like this...

The B's to my knowledge dont exist anymore... The G is the same....

Youll notice in your 90-93 FSM that it says that the 6G is normal, whereas the later years the 5G is normal.. You will be perfectly fine using the 5g, as thats what most infiniti dealers put in and recommend for the 90-93 also.... Its also a bit nicer for the higher mileage engines to keep them from fouling, as there is more stuff that can get past the rings than when it was new....

I personally don't like the "Search" post myself. I find that answering the simple repeat questions tends to foster a better mood in general. You also gain more respect as a person on the board when you offer up somthing constructive. Trust me, I know how aggrivating repeat questions can be, I mod the KADET section. If I had a buck for every time I answered the, "How much hp do I get when I install a turbo" question, I would retire tomarrow.

No way. I had that exact same avatar a couple of months ago and the mods deleted it for me.

Always nice to look at, though. Breast exams really do save lives!

So do you really prefer a Groundhog day scenario where it is repeated over again and again and again and again and again and again and again and again and again.......until it becomes quite monotonous and no progress is achieved?

Q45tech is reponsible for at least 80% of the data on this board. I personally think it is a waste of time for him to have to explain the wheel everytime someone asks. I would rather he continue in new directions so the breadth of information can be greater, rather than repeated for those who are too lazy to perform a cursory inquiry. Why drag the content down to the lowest common denominator? Many other boards have done this. The quality of our content is vastly superior to almost all other automotive forums because of the standards of the members here. Most members come here to learn, not just to see themselves post already answered questions.

And if the Groundhog day scenario is the goal, what function is the Search button designed to serve? Maybe it should be disabled and we can sit around and just BS and be good old boys and girls.

Should I ask the turbo question again now?__________________Brian1995 Q45 & Q45t & 2000 Q45

I'll offer my "middle ground" suggestion. I try to help "newbies" learn both about the topic of their inquiry and the "proper" behavior/practice on a (or is it this) board.

Sample reply:

A search for "spark plug" in the Infiniti Online Mechanic forum

Returned several good results, the best one contains a great post by the expert Q45Tech, about half way down.

I'm a little passive aggressive that way. And I over use ""'s.

[PalmerWMD]

Ok folks, I hope I wont have to close this thread, it would be a first for the Infiniti forum.

I see both sides of the arguement and in all fairness, Brian has made <many> posts, that contribute to the site beyond just saying "search".

We will all maintain a friendly atmosphere, so I dont have to lock the thread.

Fred...

gotta admit thread is kinda entertaining.

[elwesso]

Yeah, plus we had non infiniti guys intervene.... This is a special thread!! WOOHOO!

Everyone talks about getting OEM NGK plugs so my question is can we buy the OEM NGK's at any autoparts store? Or can they only be purchased at the dealer?

In my experience with Nissan, Honda, etc, a dealer can source the equivalent plug as opposed to the proprietary plug at a lower price, make more profit, yet not cheat the customer.

The B's are alive & well, per NGK tech as of this morning. But, for instance, I can buy NGK plats for $7.50 ea, whereas a spec plug can go for as much as $17.50 (list).

As far as the "Go Fish" rhetoric, the good ones of those that are well beyond noob remember they didn't start out that way. Also, not everyone has enough presence of mind or experience to know what list etiquette entails and might be committing a faux pas unintentionally. Noobs who are publicly scorned go elsewhere. It doesn't mean they don't have anything to contribute, but we can catch more flies with honey than vinegar.

Additionally, the sometimes complex text query required to achieve a desired result is difficult to perform. Q specific stuff is few & far between on the site in general. Most of my searches resulted in dozens of pages of S13, 14 & Z32 stuff.

The Q pilots need their own forum. Of course if I did a search on that subject I'd probably get an answer to why there isn't one & wouldn't bother asking, even if the situation has changed since it was proposed before.

Back in the day, when I first got my J and was hungry for info, I came across the old Yahoo site. The posts were all chronoligically entered so I went to work. I figure I read about 25K posts. All Infiniti but not all J related. Everything auotomotive was in there. I consider it my automobile "high school" education.

When NICO was established, the Inifiniti thread kind of stuck to it's prior roots which was all Infiniti all the time. There was a brief moment on this new site when the J's were assigned there own area but this was remedied and all the Infinitis were thrown back together.

There is a difference between the Infiniti area and the other areas of NICO or any other car type sites. There is very little brawling here. Mostly, it is mature discussion between afficianados about finely engineered Nissans. Let's keep it that way.

If you want to brawl - which I do like to from time to time :icesangel - I head for the general section and take no prisoners. I have personally caused more threads to be locked down than probably any other long time member. Right, AZ? However, I'm here for Infiniti decorum and discussion.

There is a wealth of info archived here. The search function is useful but I don't mind answering newbie questions.

Fred, perhaps if flame wars erupt in this section they should be kicked out onto the street (AKA the General Section ) were the guys can go no holds barred.

As far as getting the plugs at an autoparts store, Ive seen them at advance and autozone... For $17 a plug.... Joe's are about $7.

[1qckser]

Ok seeing how we are on sparkplugs, you guys that are using the juice/ N20 are you still using the platinum plugs or did you go with somethin like the NGK V Racing cooper plugs, the reason I ask is because it has always been said that nitrous does not like platinum plugs, and I have seen 2 se-rs juicen running platinum plugs and they caused some serious headaches, I know Heavy has an answer for me, and no the search button did not help with this question.

[1qckser]

OK never mind I answered my own question, this info is from NGKs website

Can I use platinum plugs with nitrous injection?

No, it is not suggested to use platinum plugs with nitrous oxide injection. There have been instances where the platinum tip has lost its bond to either the center or ground electrode when they were used in a motor with nitrous. Thus far the tech's say they have had no problems using Iridium plugs with nitrous.

Is Joe using G's? If so, then that would make sense with my statement. AutoZone, etc is not the place to buy plugs, try sparkplugs.com. But, if Joe has the same plug, but a "B" for 7.50, that's a deal. Sparkplugs.com sell them for $11.00.

Yup, V Racing copper, close up the gap 10% from stock spec, and with a 100 shot, I use one range cooler. If we use 5's stock, I'd go with a 6. With a 50 shot, I would keep the original heat range. Or even better, Iridiums, but you guys tell me I shouldn't use them. I hate running copper if I can opt for Iridium.

[AZhitman]

Wes, do you still have the hookup with that guy for NGK's?

p.s. Glad to see someone besides me is being referred to as a "cranky old man"...
