Perhaps you may be interested in reading Eric's review of one particular O2 housing. Here is another review on a different O2 housing.


As you already hinted at, it generally comes down to your wallet size and what you want to pay for. Obviously, effectively porting the OEM O2 housing is free with the right tools. But it depends on the company/product you decide to purchase. How severe/subtle is the tubing coming from the WG? How smooth is the inner walls? From what I have seen, most well made housings are good in the performance aspect of things, but some people don't want to pay the price. If you can get a good deal on one, then you probably will be happy with your decision.

It seems like a decent piece. However, I would be skeptical of the seller's feedback rating seen here (as of yet, he has none). Perhaps you know the seller personally, or perhaps he is trustworthy member. Either way it looks like a well made O2 housing. Just be careful of sellers who do not have some feedback ratings from other (trustworthy) members. From what I can see, he currently has zero posts and has recently joined that forum. Those type of profiles I would stay away from.

Performance gains all depend on your set up as in what type of exhaust are you running, what turbo, what manifold etc. But you should get a decent gain in something somewhere in the powerband from that. I have the evo3 o2 housing and once fully ported out is a good piece. The stock o2 housing is rather restrictive.

Don't know if you have had to deal with this yet but its something to think about... if you have a large downpipe and o2 housing a lot of times the stock oil filter wont fit or will be touching the pipe, either way you have to either get a smaller filter which sucks or a relocation kit. im currently using a miata filter from mazda that seams to work well but its really really tiny. Like i said just something to think about... good luck.

This has been known for a long time. Most people (including myself) resort to using the Lancer Evolution VIII series OEM oil filters. It's a direct fit and something like 1.5 inches shorter.

I actually bought the xspower one posted earlier (that exact one from that member) and it is great.

Here is a tip though. When you go to replace the o2 housing, go ahead and get some new gaskets. I got the copper turbo inlet and a copper exhaust mani gasket from FFWD and the seal is great. A dumped o2 is not nearly as loud as everyone makes it out to be (at least no in the car. It helped to solve my creep problem since I am running the 16g (or trying to) at low boost.

so it is real easy to bolt on. i am swaping turbo's to a 16g so i figured this is a good time.:thumb:

I wouldnt say its a "real easy" bolt on, but not very hard either. Its just a really tight fit. Ive installed a dumped 02 with the turbo on the car many times, and I have big arms/hands. You just have to be prepared to get cut, but you can take off and replace every bolt on there without taking the turbo off :)

I thought it was really easy and I am by no means a pro mechanic. Just get plenty of PB Blaster and some good anti-seize. Go ahead and get all new gaskets for sure though. Advanced Auto actually carries an oem set for just a few bucks (o2 housing, turbo, oil return, and some other misc. gaskets and stuff) pretty good deal.

I love my copper gaskets though and I recommend them!

Thought i read somehow that some o2 housings will not be in the "exact" same spot/position as the stocker so if you got an aftermarket DP it wont fit correctly? OR is that just with the evo o2?

what does it mean by o2 dumped does it eliminate the o2 sensor? and what does it mean by recirculeated. i saw the recirculaed ones, have two tubes and they are together im assuming keeping the air in the system. what is the advantage of one that is dumped? and what is the best one to run with a evo 3 16g set up?
