mine went in 1,2,3..fitment was perfect

 

the best gains have been shown for the ebay ss o2, even BR tested it against there ported and coated 02 and the ebay o2 performed better

 

depends on the mods, but i'd say 5-10 ish

 

dynos been shows 7-14 whp gain with an 02 housing
buschur got 14 whp on their dyno with the ebay 02 housing ..

 

for 60 bucks its a must have

 

gotcha...e-mailed the seller twice and no response so idk but overall you guys have good feedback regarding the ebay o2. Getting a 3 inch tbe so mating that up to the ebay o2 should give me a badass sound and nice gains after a good tune.

 

Watch for our groupbuy very soon on these!

when is this group buy looking to go down?

 

Once we get the batch back from Swain we will be opening the GB.

 

The one it comes with is a piece of $hit. Buy a new one from or reuse the original. BTW i got mine coated because it looked a little thin, dunno but i think the coating will help against cracking.
