I see there are several on the market, do they make a noticable difference on performance and economy?

 

I put the CFM+ intake on my '06 and immediately noticed tons of bottom-end power. The turbo spools much faster compared to the stock intake.

MPG wise - not too sure. Probably gained something - quicker off the line means I need to apply less throttle pressure to get to the same speed.

I also installed a CFM+ on my '06. I noticed much quicker turbo spool up and a whole lot better throttle response. I too don't know about the MPG yet, but all and all, I would buy another one.

 

I got .8+ out of my homemade airhorn. I built it for max flow... not for looks. It's 3.5 dia. and the biggest radius possible and still fit under the hood. It's in my avatar. Craig

 

Here is a link to the tests that Erik@TVP in Dublin,CA did...good numbers....I have a GDP Intake horn myself.....
