True. I just saw online that someone added a aftermarket Intake Manifold Gasket and got a 4whp increase on a dyno. Pretty good. Lol.

Time to borrow someones car! Lol. If you sent it on time Monday for overnight shipping. They would get it Tuesday at 11am. Then if it was same day turn around you would have it back Wednesday. They got mine today, So I'll keep you posted.

My friend has 3 cars so he borrowed me his Dodge Ram, I'm not a truck kind of guy so I feel weird driving it. Lol

Did you notice a difference because I installed mine with the air filter so I couldn't tell what part really made the difference but it is really easy to install nice pics

ok..my review.. so ive drove about 45 miles today playing around evaulating spacer. only other thing ive added to car was k & n filter i added a couple of weeks ago. as far as the spacer ive noticed i little more aggressive tone at wot...nothing majior but more than before. accerlation seems to have picked up slightly with a smoother pick up of speed. im not talking big increases...barely notceable to me but it is there. im guessing with a proper intake you should see more out of it. the eclipse i had years ago that had a cai on it with spacer had a very pronounced whistle to it during accerlation but i have not noticed the whistle with this one. also, i added spacer on my eclipse a month or too after cai and i noticed more of a improvement than ive noticed so far with this car so im hoping for a bigger gain once i get a intake.
