Cold Air Intake
 

I'm looking to buy and install the K&N 69-7078TS cold air intake for my 2012 Roadster. I am moderately mechanically inclined. I downloaded the installation instructions and it looks pretty straight forward. Anyone have any experience installing this particular modification? Any suggestions on other types of intakes that might be better? Also, will the installation of the intake system void the warranty? Thanks for all your responses to the squeaks and rattles post.

I'm sure hundreds have.
Honestly, it's a warm air intake. Pass on it. Get a Stillen G3 or an similarly designed one

:iagree:

Any even cheaper solution than the Stillen G3 would be a Silicone Post MAF Intake tube with the K&N drop ins if you don't want to take off the front bumper.

^Agreed, I did this and am happy with the results. Stillen is a fine choice if you are willing to do the install and have the filters somewhat remote, but I didn't want to deal with that. Like people have noted, we have a CAI already (albeit some improvements can be made).


No regrets here.

Cold Air K&N s
 

I did the same K&N s on my roadster. Easy install. Not exactly factory perfect, you have to be somewhat innovative. The rubber hoses have to be cut to the right length, and in some places you will need to lube the end of the hose to make it slip over a nipple. Be sure you turn the hose clamps where you have access to the nut. The Mass Air Flow sensors MUST go back in the same way they came out. forward facing forward. No exceptions! One of the K&N tubes I received, the port for the MAF was welded in backward . Engine just will not run right with this. K&N sent me a replacement tube, but I still had a lot of mental anguish and had to take the car to a shop to have the ECU reset. But that is rare. Don't let my experience with this deter you . ALSO, falcon fixer is right, they are still warm air. Not really any performance gain, no matter what they say. I saw a real test (England ) done on cold air intakes and there is really hardly any gain in performance. I just wanted the sound when accelerating hard, without the constant loud drone of aftermarket exhaust, nor the expense. I did get the sound, and I'm happy with the K&N .
Hope this helps.

Excuse me .....DepointFive o ... it is still warm air.

^I THINK you are talking about the YouTube video with the R34. And the guys are from Australia, lol

If you are talking about that video, those guys should be shot. It is such a bad test. The R34 has a turbo, meaning it has an intercooler, thus making the "cold air" not that important. The turbo heats the air so much that the intercooler is really the think making the cold air important. (I hope that made sense)

And if it's the other episode where they test the chappy POS blue car, they do the equivalent of the K&N, it's just a cone filter

Cold Air Intake
 

Thanks Chuck you brought up some good points. My friend mentioned that by installing the system it may void my warranty. Is that true? Gene

Installing a CAI will NOT void your warranty. To void your warranty the dealer is required to prove that the aftermarket part caused the failure, and unless you drive through water high enough to fill the filters, there's no way they could do that.

Exactly. And you can always revert to stock.


If you ever go to the track, You void your warranty too :tiphat:

Just make sure to wrap those ac lines, that won't be covered under warranty

Voiding warranty
 

From my actual experience, the CAI (or other after market parts) do not void your warranty. BUT the dealer can and does refuse to work on the car until you put the stock parts back on.
And to diddy535, I didn't understand the part about wrapping your AC lines? Please explain. Thanks

Not if the parts have nothing to do with the claim. You could legally force the issue.

i had the very same concerns that you've raised about making sure 'forward-faces-forward'...my last oil change i was allowed to be in the garage with my nissan's dealers top mechanic. he said that my "opposite" facing sensors were indeed okay, and that the car wouldn't run AT ALL, otherwise...

i sure hope he's right...

it's a fairly easy install...i did it and i'm old and feeble, anymore...the one trick part, besides getting the nuts on the bolts in the new cans, (and making the rubber molding look HALF-WAY-DECENT), was the passenger side L-shaped tube, it crimps if not cut right...my mech. corrected it on my 1st oil change (before my 2nd one where i axed him about the sensor placement.)

i chose the K&N because i wanted an hp increase and wanted to do the work myself...i knew of their rep. from their highly regarded filters...i wasn't real keen to knowledge about the stillen, butt, knew i didn't wantta take off the bumper, esp. for a filter cleaning or change (plus, water.) also, i bought the red nylon covers for the filter...a nice bit 0' color in the bay...

p.s.---they ROAR at 4k...nice compliment to my FI pipes...

Glad you like the sound, previous cars I had the warm air intake. The open filters in the hood do make a nice sound but on the Z minimal gains compared to the cold air but hey for ease of checking on filters and you got the sound you wanted thats all that matters. Plus your FI pipes are giving you good gains anyway! I bet it sounds real nice.

it sure does, sir...it does, indeed...

I installed K&N Typhoons on my Nismo, and their "hot air" intake burnt up my MAFs; not once, not twice, but three times.

It was not an oil issue, I believe K&N when they make that claim...it was a heat issue. This intake is open to the engine bay, and pulls way too hot of air in; killing the IAT on the passenger side MAF.

I'm in the process of putting the stock intake back on now, with K&N drop-ins.

CAI's ,a write of passage for most when we get the car.

Honestly,they do not do much(if anything)in the way of real power.
For sure,you'll get that great sound from the added air being sucked into the
intake. Your MPG will prolly drop from the extra revs to hear that sound...

Performance wise,K&N's in the stock airbox will do as good.
Won't look as sexy though.

I'd just do PopChargers if you got to have a intake mod.
Cannot see the logic of remote filters stuck down where you cannot easily reach e'm
unless there was the power gains.

Just sayin...

OP, this will be useful for you:

What's the point of these? It's says they do nothing performance wise, I just don't get spending $108 for nothing unless I'm missing something.
