K&N Air Filter in Stock Air Intake Box vs CAI Comparisons - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

evonschu · 03-09-2014, 03:42 AM

Just curious if anyone has done any comparisons between putting a K&N air filter in the stock box vs CAI? I bought a K&N filter to put in the stock air box when I bought my ZL1 last year until I did proper research on CAIs. Wondering if its worth the $400 for a Rotofab vs a regular K&N filter only. If its like the diff between 5-10HP not really worth it.

It all depends on what your looking for More power, sound, bling for your engine compartment ?

I have wondered this myself. I am not going racing, I just want something to make my engine breath alittle better.

I have looked into the SLP Air Intake Tube also but again $200.00 for 5-7HP HP.

I am on the fence post untill I get car out of storage then after looking at posts here and asking questions like yourself I will pull the plug.

Are you talking about just replacing the filter element, or a new CAI system?

If its just the element then honestly, who cares, I would not pay the 400 bucks, but that's just me.

There are other filter elements out there, but i have no experience with them because i changed my system from the gitgo.

For my money i would replace the whole thing with either ADM, or CAI Inc. CAI intake system....with the race scoop of course.....you'll notice a difference for sure!

The Roto-Fab is tried and true. It has been dyno tested with HP gains of 25-30 to the wheels! It's very easy to install, it gets rid of that big, clunky intake box and it really makes the supercharger whine! It's a good investment.

Bigtime53 · 03-10-2014, 09:01 AM

I don't know if this is right or not but I thought I read a thread if you use any other CAI filter other than a roto-fab it would throw a code? Is that true? I bought the carbon fiber inlet tube and the roto fab filter and it not only looks good it sounds good. A little pricey but everytime I put the pedal to the floor and hear the blower whine I don't think about what it cost!

KBsSS · 03-10-2014, 09:03 AM

Mines Stock V8 no turbo....

thats why I am on the fence for now. Retune engine? codes misssing? You see i have the murphy law problem ( if its going mess up or be a pain I `ll get it )

This is all great info and all but I'm looking for some hard numbers.

Like:
Rotofab CAI has been shown to give you 25-30 RWHP increase while Replacing just the paper air filter in the stock air box with a K&N air filter in the stock airbox has been shown to give you only 15-20 RWHP increase.

again i ask are you looking for an element or complete system? imo the best way to go is a complete system i dont know of any side by side comps of element vs box

Yes just the stock filter using a k&n NOT a k&n CAI.

1KillerSS · 03-10-2014, 12:28 PM

gotcha....i would be very skeptical of any HP gains stated by manufacturer on that one for sure..as you already are...but from what i know there is really nobody who will pay for a dyno run just to see hp gains on a air filter element so thats gunna be hard to come by

He's looking for a comparison between just putting a K&N filter inside his stock air box vs. changing the entire airbox and filter for something like the Rotofab or the CAI.

from what i know there is really nobody who will pay for a dyno run just to see hp gains on a air filter element so thats gunna be hard to come by

but im sure thats why your asking

for the 400 bucks tho your 3/4 of the way to a complete system
