K&N Aircharger 21hp gain????

[MST1TED]

Looking at the K&N website. I did the whole “find your HP gain here" thing. It says the “Aircharger” part #63-1114 will give you gains of 21.09 HP @ 5216RPM’s on the 300C. Now I’m no expert, and I have had many CAI’s before in rice burners, but I find it fard to believe that I am gonna get 21hp out of this. Anyone seen big gains with this unit? Pros and Cons? Any better CAI's out there?

21.09 mental horses!!!

I have the unit on my car, sound is great, but gains if any wouldn’t be more than 5hp on the optimistic side.

No rocket science is needed to install it, but time consuming.

If u want my advice, invest in an afe stage 2 unit, it has proven horsepower, better sound and easier to install.

Thanks,

Ahmed.

I doubt that is even close....8-10 if lucky...just my opinion.Somewhere on here they didnt side by side tests on cai and if Im not mistaken afe and air hammer showed the best gains...but it wasnt 21 hp
