were can i get an cold air intake for my q45

[jose310]

i have a 94 q45t, i have called many muffler and racing shops and nobody carrie's the intake for my q. does anybody know were i can get one in the streets or online? im in L.A

Actually, you don't want a cold air intake, or rather any intake you don't make yourself won't be cold air - it'll be hot air. Furthermore, the stock airbox has been frequency-tuned to the intake. No after market intake has ever been shown to deliver more horsepower on the stock engine.

Stick with the OEM intake, unless you just want the cool sound.

.....No after market intake has ever been shown to deliver more horsepower on the stock engine....

Only because there has never been a test showing it does or doesn't have more power. It's all opinions until someone actually does a test. My intake IS a cold air intake and takes the air by the fog light. Some will say it's not as "cold" as the OEM because it's down by the ground. It's only 12" or less lower so I'll take the "superheated" air from down there.

I made one and it works great. I made another to make my turbo work and have my original if you are interested. Doesn't work on the Active model because of some components that are mounted where the new air filter will go, not sure about the "t". It's not a simple bolt on though, you have to cut a hole under where the OEM airbox is and run the new tubing down through there. Makes air filter changing a little more difficult.

It's your call, many people are convinced that Nissan made the best intake system on the planet that can't be improved upon, I say nonsense. I'm sure you'll hear from more naysayers.

Here's a link to the thread I made about it.zerothread?id=246554

Here's a pic of the one that I have for sale and the other pic is of the maze of plumbing you will be replacing.

First you have to have an engine that can utilize and needs a more free-flowing intake. Yours qualifies, qsiguy.

Q45tech has done the math. The stock airbox isn't restrictive. So, the only advantage for a stock motor is genuinely colder (cooler) air, if you can actually engineer it.

I totally agree.

Math shmath! we gotta pimp these rides man!

Yep, those dumb engineers should have saved their time designing those tuned resonant chambers, locating the intake in a high pressure area, and accomdating that near zero flow loss filter that actually protects the engines internals. Who cares if it is rain puddle proof?

When will they learn?

[qsiguy]

Never said it was engineered poorly but they have much more to consider in their design than just performance. Puddle proof as you stated, sound volume, etc. must go into their design.

Like I said, every time this question comes up the same critics chime in. To each their own and stock is boring.

[maxnix]

To each their own and stock is boring.

Usually working boring is better than improvised WAG. When TGvince did the CAI for the VH41DE, he actually had some interesting data, but while there might have been some peak gain, there was a considerable drop mid rpm that would affect everyday performance.

Q45tech has done the measurements and calculations to determine actual performance of the stock CAI, and possible gains. Without another solution like your rear mounted turbo, there is not any gain and several downside risks in replacing the OEM CAI on a stock VH45DE.

You are to be applauded for trying, but data are data. Different is not better until it is so demonstrated.

actualy not quite i hav

actualy not quit i bot myself an intake a checkers had to do some drilling to the adapter made it fit my aftermarket intake whooo man loving more than that stock more horses for sure.

[95eEra kid45Q]

i dont know if you will be able to get a cold air intake for your car but what i did was buy a spectra intake for my 95 q45 also an adapter maid a fit cut the first layer of metal underneath the air box allow some fresh air straight up into the intake and put metal box to block out engine air. my next up is exhaust coupl of flow master maybe or i might do one not sure quite wich is better.

[Q45tech]

I installed a vacuum port atop the air filter housing so it was/is very easy to use an ACCURATE manometer to measure the restriction thru oem assembly after oem filter to a point just in front of MAF.

Interesting to see the tiny restriction grow under WOT with rpm. Even more interesting is to see the restriction fall with road speed [due to oen finding the exact highest pressure point in front of radiator.

With a decent oem air filter the total restriction builds to 7" WC then declines to 2" WC at 140 MPH.

7" WC is 1/4 of a psi or 6.8/4 = 1.7% power loss at 100 mph

When you remove oem system it cause oscillations in MAF voltage bewteen 1800-2200 rpm [55>65 mph] which could reduce MPG slightly

[Infinitiguy19]

When you remove oem system it cause oscillations in MAF voltage between 1800-2200 rpm [55>65 mph] which could reduce MPG slightly

So is that why others have said that they noticed a difference by "Seat of the pants" when they added a "Cold air intake"?

Or is 2-5 HP you would get in cold temps really noticible?

[Q45tech]

Each 11F drop in intake air temperature results in a 1% increase in density into cylinders. That 1% is ~~ 2.5>3 lb'ft of torque.

Even the most sensitive driver cannot disertain 10lb/ft out of 300.That would change the total quarter mile by 0.1 seconds.

Most of the feeling is imaginary coupled with the noise and the work to make the change.

A stopwatch is your friend

I would think the oem stock system is much more likely to achieve a higher top speed than a cone or homemade cold air package. I could be wrong but unlikely since I've measured things up to 140 mph. AS If the difference between 156 and 158 mph is important?
