I havent done long tube headers yet ,,but plan to. and looking to replace my o2 sensors and only buy them once... i searched threads a found a few old threads on this.

Denso 234-4025 x2 ?
Bosch 13111 x2?

Same part # for both sides? just want to see what everybody is using now. Im leaning towards the denso for the price and reviews. Any input would be appreciated. thanks

Why not just tune them out after LT install?

Pretty sure he's talking about the fronts. Go with the AC Delco units. I've also heard the NGK ones are good.

Bosch wires are actually longer er incase you don't have extensions - loved that.

do the denso 234-4617 they are the same length as the bosch and are a much better sensor. They are oem by gm and many people have issues with the boosch sensors, myself included. I can tell you first hand that the densos switch much faster than the bosch

I vote denso. Bosch gave me problems and denso didn't.
