Does a cold air filter kit make a notable difference???
Hello all..I am currently running a K & N filter in stock filter housing. I am wondering if a cold air kit will notably boost my h.p.? Does it change the sound of your car for the better? Should I increase the size of the Throttle Body and MAF sensor?
I have had this c4 12 years and I am looking to make it more aggressive performance wise and in sound. Currently running Magnaflow exhaust.

On a stock LT1 changing the TB or MAF will only hurt you wallet and no real gains. A cold air intake is about the same unless you are looking for sound or looks. The SLP Claw will give you more throttle sound but not HP performance.

I agree. Remove your filter housing and study the area that the filter sits in. How is any filter, stock or otherwise going to get COLD (ambient) air from that location? It's not. Aftermarket "CAI"'s for late C4's are a waste of money...other than the ones where you cut through something to get to actual cold air.

I must agree...the C5 just doesn't do it for me! I like the C6 GS because it is more refined than my C4. The 7 must be an amazing car but it looks to boxy to me. I must say my 4 is snappy on the throttle and very responsive in the steering. The 300 ponies are just enough to make it come alive on the freeway as well.
All that being said we can go back and forth all day but when it comes down to it...Vettes Rules!
What do you guys think of the new mid engine design for 2018-2019?

as to not get too far off topic... i do have an SLP cold air intake on my 95 (looks awesome) and a K&N on my 92...both cars came with the systems when i bought them...but as others have pointed out, cold air intakes provide little to no performance improvement just based on the desing of the car...there are however forced air bolt-on's for the C4 but they require using the front license plate housing...which would make it illegal in most states...unless you want a $140 ticket for no front plate.

I hear that a lot too. My issue is that I haven't experienced a lot of that. While it is true that there are more things to fail, the question is how often does it fail and with that, you need to discount the "parts replacers" since all they know how to do is throw parts at it. My 7.3 Powerstroke is a fine example. The local mechanic didn't bother to listen to my mods probably because he didn't understand it. His scan tool said the Exhaust Back Pressure Sensor was broke. Fair enough. We changed it. As I told him, it only changes long term fuel trim so why would it die every so often and wait till it sat for a while before it might start up. Another mechanic suggested we check for the fuel pressure and ignition. Sure enough, fuel line was crimped accidentally and the pressure got better but the Injector Driver Module was toast. Got hot and it could fail. Cooled off and it drove. So was that 2 components that failed or 1 plus an idiot mechanic?

On my 91, there is a few HP over the stock unit when I put the conical filter on the TB. HOWEVER, that was on top of the curve and on a modified motor making 420 RWHP. Even then, you won't notice a few HP increase other than in your mind, aka "Placebo Effect". That is why I never believe the SOTP dyno.

a friend of mine that races C4 corvettes also tracked a C5 Z06 and a C6 Z06...he sold both the Z's and now daily drives a 92 zf6 and races two first generation C4's (that he has a ton of money in) and says he has no regrets. he's a smart guy and a corvette guy so i take his word for it...with that said i still may get a C6 at some time...the ZR1 appearance is so nice in that generation. but C5's arent on my radar...
