Noisy K&N intake, anyone else?

More of the 'you wasted your money, CAI do nothing" people chiming in again. Been proven time and time again that the decent CAI that do the R&D do actually produce and provide gains in HP and fuel mileage increases. I seriously doubt K&N/Airaid and any of the other reputable CAI companies would risk market share and their names by making a product that does nothing.

 

I wish I still had my dyno runs from my 2008 Corvette, I did runs with the stock setup, the Z06 airbox and a Airaid CAI kit. The Z06 system alone added 5rwhp over the stock LS3 system, the Airaid produced 7-8rwhp gains over the stock system and also smoothed out the A/F ratios as well. To get 7-8rwhp gains means you are getting almost 10hp at the motor gains.

 

10hp here and 10hp there in mods sure does start adding up in the long run.

 

OP if you don't like the noise of the K&N (the Airaid has it as well, as said once you remove the resonator the throttle noise is more pronounced) then I would suggest getting the Airaid MIT kit and a drop in low restriction filter for the stock airbox. Then mod the airbox as someone posted recently to allow more airflow into it and you will get some decent gains.

 

Less air restriction = better millage.

 

This has happened in every vehicle I've modified.

 

I had a 2002 Grand Prix.GTP once I pushed the HP up to near 400hp the thing got great fuel millage. Which helped had to run 94 in it ha ha.

No noise problem on my K&N CAi as far as I can tell, but I also have the Borla ATAK system as well
