denso oxygen sensors?

not side sensitive

The Sensors are not side sensitive but in some brands the length of the pig tails are different only allowing you to place them on specific sides. Had no problems w/ Denso in the past. I usually sell Echlin to anyone who wants inexpensive part and they dont mind that it is made in taiwon. For people willing to spend a few extra dollars i offer Bosch. You can find the Bosch ones for between $45 and $65. Part # 13127 fits 96-98. 99-04 mustangs take a completely different sensor part # 15716.
coincidentaly the 94 mustang 5.0 takes both the 13127(before cat) and the 15716(after cat) Ford liked the fast response that help lower smog emissions and decided to continue using them.

Get them from Ford.

+1 for OEM. They have a different set of standards, when it comes to o2 sensors. There's a guy on Corral that sells OEM for real cheap. Let me find th elink for you.
