What cold air intake did you buy?

[mmmpat]

Just wanted to know what sought of cold air intakes did people purchase and why, as we all know its quite hard to get your hands on some good brands here in Australia, besides APR which you can find pretty much at the dealer.

APR.

I got notification of my tax return, I saw someone selling one (Lucas R) and I bought it.

There's a good reason why he was selling it, or why anyone would onsell their APR intake.

Welcome to the forums. I'ved moved your thread to the Tuning forum, as this is where it should be. You'll already find numerous threads and discussion on intakes here.

It's worth noting that you should mention what car (MK6 Golf GTI etc), as different models can have different engines which require different intakes.
It's also worth noting that different people have different requirements for intakes. Some people don't want to remove the engine cover (on the Golf R for example) which limits your options. Some people don't mind not complying with the laws in relation to sealed / isolated intakes etc.

what cold intake did i buy? the VW one that came with the car.

i d7cked around for 20,000km's with a BMC filter which sounded great and made my wallet lighter, but then went back to stock paper media in the stock air box.

no offense to anyone out there who likes to try/tinker, but in terms of mods that you can do to your car that are great at parting you from your cash, but dont actually do anything because it's all in your head (placebo), the good ole CAI would have to be at the top of the list.

no, a drift pod filter is not going to be superior to the airbox placed in a car, designed by a german who has anally engineered things to the umpteenth degree, all at the expense of his social and love life....

just saying.

My Carbonio CAI is very expensive under-bonnet bling IMO.

Bunnings CAI FTW!

To be fair Scotty, if you look at any F1 car, you can see all the right elements of an optimal CAI, large, straight as possible, smooth inner, bellmouth shapes, insulated, ram air from the high pressure area.

There are a lot of good intakes out there, and the main thing to watch for is the ingress of engine bay air. At idle, at the lights, after about 90 seconds you start registering above 60 degrees around the tappet cover air, and if any of that finds its way back into the inlet, your response away from the lights suffers. I see a lot of well boxed, cone shaped filters on nice straight pipes, but if there are ANY gaps at all which allow engine bay air in, that's a minus over stock when you aren't moving.

Stock is however designed with noise control in mind, and unfortunatley there's only a few ways to effectively muffle induction noise, all hinder performance to some degree. I'd have to say, on an otherwise stock car a CAI will make little power difference, apart from the placebo induction noise making you think so..... With a dump and a tune, different story....

I have a Modshack, a flash bucket basically, but one made from Phenolic, the worlds best insulator, the main drawcard for me.

i should have said "apart from gregs/polarbears etc intakes" lol.

but yeah - short of a setup like yours, fed directly to the front grille with FULL enclosure, straight through, and lots of dry filter media (not oiled) i see 101 examples of "cai's" at autobarn every time i go that would be a step down from stock

Dude that bunnings setup is good. No sarcasm from me, thats good cheap air ducting where you want it.

I don't agree with the whole Intakes are a joke line, if the car can take more air, then you MAY be missing out on ponies and economy. This is likely more relevant to modded cars.

I've been playing with an intake project for the Polo, was revised again today, but as Greg said, you have to be pretty vigelant in not allowing hot engine bay air in.

One thing thats working great in my testing is a sheet of steel / ally, partitioning the engine bay. Its keeping the block heat away from my intake (for the time anyway). I'm no doubt sucking hotter air at the lights, but my spool is definitely smoother and my fuel economy is proving to be just as good when I'm not stuck in traffic.

A work in progress, or just playing... Time will tell...
