spark plugs?

[BzOaY]

I am just curious on what kind of performance spark plugs and wires people are using in there A/C?

[wade001]

use the factory ones or NGK, spark plugs and wires give pratically no performance gains unless the ones ur using are sh*t.

im agreeing w/ wade. the only 'good' plugs i'd associate w/ would be NGK (period) either the platinums or the iridiums, but our engine makes a spark at a relatively typical temperature, so iridiums aren't needed, and since they are already using stock platinums..... just keep em the same. lol

wires... just wait till ur car is 10 years+ then swap em.

[wade001]

That is unless ur boosted lol. then u need higher temp plugs

Changing them is'nt a bad idea. They do wear out, mine were a bit corroded.

I got Bosch platinum 4, pretty expensive but only 4 cyl so I think it's worth it

As far as performance gains I'm sure they are next to none.

As far as performance gains I'm sure there are none.

Went ahead and fixed that for you

i am just having problems with one of the plugs, my check engine light comes on randomly and then turns off after a sec, so i did a code scan on it and it was one of the plugs cause i changed the one that was bad so now i just want to replace all of them just in case. Just didnt know what other people were running

I thought it was a step "colder" for forced induction. When my kit was being created they tried to get an NGK plug that was a step colder and it didnt exist. So im still running the oem plugs. And doesnt nissan and most late model cars have that 100,000 mile no tune up needed.

Id replace them all if you are having a problem bzO. Not sure why you would be having a problem this far!

[BzOaY]

I don't know why it went bad either but it is just like anything else, just cause there is a warranty doesnt mean it wont still break or be deffective

[dldjros69]

i hope you just had a defective plug and not something else wrong with your engine.

If memory isn't fooling me then im quite sure it's higher temp plugs because u run hotter or along those lines (read an article about it years ago). but it depends on how much boost your running, higher the boost the higher the plug temp.

what does the plugs node look like?? can you post a pic? depending on that u can possibly diagnose a problem if you have any with your engine because with todays spark plugs should last a good 60-100K miles.

[BzOaY]

i would but i replaced it at the store and they threw it away

[wade001]

did it look like any of these? http://www.gnttype.org/techarea/engine/plugs.html

Yep, step colder. And yeah, no step colder plugs exist for our motor because the plugs are not the same as the previous generation QR25DE. Our plugs are longer and different.

lol, i stand corrected -_-

Sorry, the 2008 Altima does not have spark plug wires. Each cylinder, and the corresponding spark plug, has it's own ignition coil. The 2.5 has four ignition coils, the 3.5 has six coils.

ahh- touche- that big a** plastic lookin thing.... good call throck
