I am (still) waiting to receive the Y-pipe, cat, and CAI that I ordered from WSP and guess what happened. Got a CEL. This only seems to happen while I'm waiting to get mods...Anyway, the CEL is for knock and rear o2 sensors and I was wondering who has the best prices for OE replacements? I visited Courtesy and the o2's are $117+ each and the knock is about $135. Are they available anywhere else for less?

I am planning to replace all three o2 sensors to avoid any future problems and it will be nice to feel the difference with a Y-pipe, cat, CAI, AND all new sensors.

Any suggestions would be helpful.

 

I just ordered the Bosch oe replacemenst from
PartsAMillion.com
