first off i have been trying to find the best price on ac/delco/delphi o2 sensors, does anyone have any leads?

as far as the extensions go i have found them at jegs, summit, and speed inc. does anyone have any other options. i have thought about making my own extentions but i dont have any leads on where i could find the proper connectors and pins. i am fully capable of making them myself, i would rather not splice into the engine harness if i dont have to.

finally the header gaskets, i am thinking of going with percys seal for goods seeing as those seem to be the best sealing. i have only been able to find them available directly from percys website. are there better sealing out there?

i have searched through all the supporting vendors on the site and i couldnt come up with anything about these items. i have also searched old posts and cant find much in the way of this type of info on where to find these items. thanks for any input and have a good one.

 

Try streetsideauto.com i find some really good parts on there and fast shipping. i believe thats a really good site for some parts. check that site out and let me know. if u want to buy something, heres a coupon that u can use to get 10% off...save10, type that in the checkout box

 

Shoebox has a couple links to cheap GM parts (O2's):

Been continuing my searching and my best place for o2s is through my cousin who works at a local autoparts store and can get me delphis.

now for those interested in making their own extensions i found a site that sells connector kits as opposed to a lot of connector sites where you have to pair the connector with the proper pin with the proper boot etc. here is a link to the connectors i believe are the same as the flat 4 pin o2 connectors.

are these correct?
this site also has tons of connector kits even some opti harness related i saw.

another question comes to mind: what about the actual wire to use in the homemade extensions. what should i be careful to watch for like gauge etc? any recommendations?

i only link to these because i could not find these things under any of the site sponsors, if site sponsors do have these i would gladly buy from them.

 

I got mine at Speed Inc. since they're nearby. Thunder Racing has a lot of good wiring stuff usually.
