Cold Air intake

Redrunner · #1 06-17-2003, 12:08 AM

If you add a cold air intake to your stock engine ( like my d16y7) can you feel more power. and can you feel the Hp increase. and is the short ram better.

CAI is better and I think I could feel the power difference but it could be all mental.

There's a bunch of posts here on the same subject. A search would'nt hurt.

most brands that manufacture intakes have charts that show the hp gain. i know aem's website does. as far as noticing a difference, i would have to say no. it will sound better though...

So what is the best one to buy would you get one off Ebay

i would go with AEM personally, they are the top name in air induction systems. injen is also a good company...

Why pay 240 for name brand when i could get the samething for 20 or 30 WHAT MAKES ONE BETTER THEN THE OTHER

this is to hard

the FILTER is the important part. AEM uses K&N filters which are proven to improve horsepower. i don't know where you get 240$ from...i paid 77$ for my AEM intake...and that's the short ram by the way.

on the aem website, the short ram had better performance increase than the cold air intake...hence why i chose it

ok you sold me I think That what I am going to go get

what do you know about getting my speed and rev limit to go away

On my hatchback I did a ghetto pvp piping one for the heck of it b.c I had no money and I had a filter sitting in my garage

Even with that POS tho, I _definately_ saw the numbers in my gas mileage. and I was able to see it in my racing also... keepin up better with the non-POS cars

there are two factors that go into making the piping of the intake effective.....volume and velocity. The problem with this is that the two are not mutually exclusive. The higher volume the piping can handle (i.e. the bigger the piping)...the slower the air actually moves through the intake piping. So big companies like Injen and AEM have spent millions of $$ developing what they feel is the perfect diameter for the piping. It is also believed (maybe proven) that if the air is cold, or cooler than your engine, it will perform better because cold air is more dense..... hence the cold-air intake concept. Simply all the CAI does is take the air from outside of your engine bay, usually from under the fender. In theory then, a cold air intake, with the correct piping, should add power to your engine. Well... not necessarily. There are alot of problems... 1) your engine is so small and powerless, that it won't even notice the minute difference in air suckage, whether it be cold or hot 2) the OBD computer in your car is too intelligent to allow you to adjust the airflow without making a few changes of it's own.... it is engineered to react to changes in airflow...... all of this stuff.... so it re-balances it's little computer numbers and kills whatever small gain you might have gotten.... so my suggestion is this...

get a K&N filter because they're simply the best performing and safest for your engine...and find cheap piping.... maybe even a cheap intake off an internet auction or something and put the K&N filter on it. And if you're interested in gaining power, you unfortunately won't do it with just an intake. I always suggest to EVERYONE that one of the first mods that you should think about if you're serious about gaining power is a new re-mapped computer that is set for these modifications.... otherwise you're spinning in the mud. And regardless of the computer, you won't show gains until you modify the spark and fuel aspects of combustion. Ask anyone who has forced induction (i.e. supercharger, turbo).... you can push all the air you want.... but you're car won't react like it should until you are balancing it with the right amount of fuel....and the right spark. 3 things go into combustion.... forget to modify one of the 3 and you're left with a soap box car with alot of pretty gadgets under the hood.

Sorry to be long-winded.....

in respect to your rev-limiter and speed-limiter.... a new computer can alter these as well. Another option is an MSD ignition which comes with different rev-limiter settings that you can adjust. Unfortunately it's not a simple matter of cutting a wire....or pulling a fuse. You actually have to replace or confuse the computer in your car.
