air intake questions

I was talking with a friend about cold air intakes (since I don't know so much) and he told me it's not worth the money. He's suggestion was to just get a K&N air filter and I'd be just as good.

That seemed a little weird to me so I thought I'd ask the guys on the forum


Also, I was wondering if there is a different between intake brands like Injen, Greddy, and AEM.... to cheaper brands like Ractive. I found an Ractive intake (I believe short ram?) here: http://www.carxpressions.com/performance/ractive_intakes2.htm for $53 ... I'm not going for a street racer, just a nice performance upgrade.

Any opinions will be appreciated.

Thanks.

Am I asking a stupid question or does no one help out around here??

the 1 on the sight is not a good one it is just a filter and adatper not a pipe soo you need one with a pipe let me find one

here you go

A cold air intake IS going to help you. Have you ever notice the increase in performance in the cooler fall, than summer. Colder air is better for detonation. Hence why people use Nitrous.

Cold air is more dense than hot air because the molecules in cold air are packed closer together and move less than the hotter molecules which are bouncing around like crazy. You are getting more volume into the cylinders because of this principal. For Every 10 degrees you can lower the engines air temperature, you gain 1 percent power, Generally speaking.

Wait are we talking on a turbo car? because a cold air is non exitsant in that case sine the air be taken threw the filter go in to the compressor housing and gets heatted up so a drop in filter is just as good i guess except the restriction of the air box

You are correct. This estimate is only applicable on N/A cars. And now as I look at the picture, I see this is turbo plumbing. My mistake

true but a intake on a turbo still helps the factory is not that good is what ive heard

It really doesnt help much with mnor modds. the stock intake is restickive but really you wont gain anything noticable by an intake on a turbo car other than the sound of SPOOOLL

it helps the turbo to breathe, but again for every engine parts(aftermarket)...dont forget to re-set the p.c.u. some turbo will have a sudden p.s.i. drop w/ aftermarket air intake system. these confuses the p.c.u. but overall, its all good when p.c.u. is re-set.

true...true..in my opinion, if you buyin intake for turbo...make sure its the whole system.( i.e. intercooler pipes / intake pipes and b.o.v.)filter alone aint goin to give you that boost. all you gonna hear is that loud air intake tract / spool. so, do the chemistry. free up the power by lettin the turbo breathe easier, but also find a way to spit excess air/gas out.

i instaled the intake shown in the pic i had my car dynoed befor and after i gained 8.5 hp with the intake
