maybe putting a bigger air filter for more air flow might help. that's what i did with my first civic and i got better performance.

 

for the performance increase u will see... It will be worth the few MPG.

 

yea ur not gonna lose that much mpg. you will still see double that at least over the 5.0

 

Hi Again...
I'm kinda curious as to what make and model of CAI you put on your ride.
Some companies claim H.P. increase and some dont give any back up what so ever...

I use a couple of different brands on our cars and they did seem to make a difference in the kick in the *** kind and of course the sound in the ears kind..,

the short ram will sound better than the CAI and give you better low end kick...

The CAI will give u more Hp overall, but takes some time to kick in (because of the longer tubing)
All the top brands will give you the same output (AEM, Injen, K&N, ETC...). If you get a cheapie one from Ebay or something... just buy a nice filter and it will be the same thing. Its more the filter than the tubing.
