I am putting together a cold air intake for my 2.2 1995 honda accord ex. Someone said to get all 2 inch tubing, i was going to get 2.5 but they didnt have it. I have all the 2 inch piping but it seems small. What do you guys think? is 2 inches to small for a 4 cylinder? should i up it to 3?? any ideas is good.thanks
2 tubing will be far too small. you will require at least a 3 and there is no need to move the battery unless the custom tubing you choose isn't flexible at all. once you remove the factory intake hoses, box, and resonator, you will see a hole in the body of the car where you can poke the tubing down to place the filter. make sure you do get some sort of dry adapter like sky, so you will not hydrolock your motor.happened to my accord. also, why make your own when you can find a generic cold air intake on OKorder for around $30?
I disagree with Roger. Injen CAI(cold air intakes) are DYNO PROVEN to add 2-7 horsepower depending on existing mods(header,exhaust,etc.) But to see these results you will need to have your car tuned or your ECU reflashed so your ECU can read the new mods you added. Like Roger said the stock intake you have is decent, but you want bigger piping to allow for more air flow. Now on my CRX, I have a b16 swapped in and a 3 inch custom CAI with a AEM dry flow filter. The piping doesn't matter as long as you get a good air filter. I had to move my battery to make it fit, You may run into this issue, but my engine bay is also a lot smaller then yours.
stop wasting your time a cold air filter is one of those things that mis information has created a lot of hype over nothing. By iitself it does nothing and in fact the air filter on your car now is a better one alrready as it is a true cold air filter now. Go look it comes out of an air box on the inner fender well where it is protected from rain water as well as road debris and bugs. this stuff is designed to work in conjunction with improved exhaust and improve intake which means more fuel and air. This involves a lot of money especially on a smaller engine and keep in mind your car is working almost to the maximum potential designed by the factory sso anything else that makes it work harder can also help it to blow up sooner. I checked with my mechanic before I did anything because I was aware already that my car engine may not be right for the upgrades I thought I wanted and was not sure if they were worth the money or my vehicle was up to the challenge. And sure enough it was not going to get these things either mainly because of the horror stories ZI had heard from my mechanic of messed up computers to damaged engines things like that. and that is just the tip of the icdberg . I have found a fair amont of information since that time If a car is made to use a cold air style filter from the factory thats one thing. If it has a built in capacity for more power and better exhaust stronger internals among other things then that is a whole other ball game.but stock grocery getters are probably not the best thing to try and make hot rods out of.
