My mods in my signature...Just want to buy it because it is cheap. I am looking for greddy one. Is it worth it? Hard to install?

Thanks

i dont think its really necessary, but it definitly wouldnt hurt to have one.

most stock "snails" dont requrie that you have one. Most I have seen with stock turbos never have anything in the cans, even with media in them. If you ever upgrade to bigger turbo with higher boost you will absolutely need one. My catch can when I had my VF39 never had a drop in it. When I switched to my setup now, there is a minimal amount that accumulates in the can. They key is to put some media in the can that the oil particles can stick too....

No one needs any of their mods, they just like to have them. So no one is going to give you a 'Hell Yea' on a catch can

A catch can keeps the engine bay cleaner from blow-by oil. IMO I wanted one so my engine bay stayed cleaner than usual. Install is not hard at all.

+1 i just bought a greddy one from a member here. i'm still on the vf39, so i know it probably won't do much, but it sure is purty! bling ftw!

Oil seriously lowers the octane of gas. Get oil into your intake ... enough of it ... and be rewarded with inconsistent performance due to pulled timing.

It has zip to do with keeping the engine bay "clean." The breather lines don't vent to the engine bay - they vent to the intake.

The purpose of catch cans is twofold: 1, they trap blow-by liquids that would otherwise get into the intake which, as Wolfplayer already stated, reduces the octane of the intake charge; 2, they act as an "early warning system" for your lower end. IOW, if they fill up all the time you've got a motor with bad blow-by that is on its way out.

Others are correct in that you probably don't need one at all with the stock turbo, but if you go "big", you'll want one - preferably two.

Far be it from me to argue against bling!

I've heard running the snot out of your STi (even with the stock snail) can cause blowby oil to the intake which can first show up in the TMIC. If you pull your TMIC and there is oil then maybe a catch can is for you......Please correct me if I'm wrong.....

Here's a link for DIY....

I've seen other versions with fuel filters with paper elements in them.....

Nope, you're right. Anytime you have oil in the pipes, you want a catch-can.

when I removed my stock TMIC to do my oil pressure gauge, I set the IC in a cardboard box for a couple days, outlet down. When I went to reinstall it there was a little oil in the cardboard box that had run out of the IC. This was within the first 3000 miles on my odo, so the engine is still far from fully broken in, but I want to add a catch can just to keep the IC clean.
