K&N Cold Air Intake - IS IT SAFE FOR A 2004 z?
Hi all. Brand new member here.
Yes I realize topics about CAIs are the most common around here. I did my research before even signing up to ask this question . My concern is not about HP gains and sound or anything like that : my question is it is SAFE for my 2004 Z? Money isn't the issue , I already bought it but can return . My stock air filter box broke and it's about $160 to replace OEM, and I already had the drop in K&N filter . So I can either replace the broken filter box with the new K&N Cold Air Intake or order a new OEM filter box and keep using my drop in k&n filter . My main concern is if the cold air intake is safe for my cars engine . It's an older car , 2004 with 142k miles on it. I don't want to get it the CAI and have dust and particles damage the engine . So for the more experienced owners on here , is a cold air intake like K&N safe ? PS I am not talking about the Typhoon, just the standard K&N Cold Air intake that sits exactly where the standard filter box would be. Need to make a decision soon ! Thanks ! |
Go for it. I run K&N CAIs on all my vehicles including the Z. Proper filter cleaning/oiling and regular engine oil changes and you'll be fine.

Don't forget a twice yearly MAF and TB disassembly to properly clean them, too.
Ditched my Typhoon intake kit because of that, and because it occasionally shut off when I stopped at a light due to sucking hot air into the intake. Do with that what you will. My car made 292 to the tires with a stock airbox and stock filter, FWIW. My opinion? It's justifiable to attach an aftermarket intake to the Z if you convert it to a bigger TB and MAF piping. But on a stock car with just a tune and bolt ons I'd stick to the stock box with a non oiled performance drop in filter. |
Actually water is your biggest danger with an aftermarket intake. A friend went through a deep puddle and hydro-locked his engine, had to change it out. Make sure your bottom shroud/cover is in place if you run one. A salvage yard should have a good price if you choose to stay stock.

Or is my understanding wrong? |
If you're referring to the short ram intake, then you should be fine. It's not really a "true" CAI since it's not drawing cold air from outside the engine bay any more than the OEM intake.

Agreed, thanks!
Yes,a short-ram with a shield should work fine without the added risk of hydro-lock. You will have much more induction sound but higher intake air temp (It will not improve performance at all.) When I installed my Z1 "CAI" I measured only a 5-6 degree temp drop from stock position, so the original airbox was a great design for temp and water but keeps the VQ quiet. If the tube diameters are the same you won't need to reflash/tune the ECU. gl! |

Thanks! Is it obnoxiously loud ? I'm more into deeper rumbling sound than the loud , high pitched sound you often find in souped up old Honda street racers for example
My Typhoon had it's own "sealed" box and it was still ****. If you don't want to learn a lesson for free that cost me $500 (typhoon + a new stock airbox) then by all means, feel free to pay it as well. |
The induction sound from the conical filter isn't that loud. It kind of sounds like a hiss at idle and a "growl" under load or WOT. It's hard to describe but definitely different than the typical eBay fart can noise...
Or whistle tips. [Insert Bubb Rubb video here] |
Just wondering why you would want to add this? Seems to me there are a lot of problems (in general) with mods to the stock setup and sounds like it needs some periodic maintenance.

I've been running a K&N cold air intake for about 57,000 miles and it's fine. I think the model # was 57-6013 FIPK. I'm 100% satisfied. I've been using the same filter for all that time - just clean it, let it dry, then spray it with that red oil you get with their recharge kit and you're set. Definitely performance increase from 5000rpm - redline. Nice little air suction sound when I punch the throttle too. I don't remember what it sounded like before but I seem to remember thinking it sounded more aggressive when I got it back in 2012. Also the throttle body isn't dirty at all so I don't think there's any particulates getting in there.

when i had my z i opted for the dry filters, same thing with the vette. less maintenance, just water hose from the inside out, let dry and put back on.
btw, dont listen to jimbucks, just look at his posts |

Yup that's the same one I got! Good to know from a first hand owner . I appreciate the response !
I didn't do this and just let it sit on the saddle bracket which caused the whole thing to sit a fuzz too low and eventually the heat shield rubbed through a metal line that runs underneath it. |
