Denso Oxygen Sensor - 234-4124

Inexpensive, well-made, and even comes with its own anti-seize packet!

Fits an AP1 S2000. Works like a charm.

A lot of reviews saying this is perfect for Honda S2000's replacement. I installed this after my original 02 sensor went out. Now my car bogs during light or even sometimes full throttle due to this NEW sensor sending a lazy signal. Now too late to return =/

This fit my AP2 S2000 without a problem. It even came with the clips to secure the wire. It arrived in good time too.

This works great on my S2000. Economical direct replacement with quality fix.

With limited confidence in Amazon' part finder, I confirmed with Denso's website that part 234-4124 correct fitment primary/upstream oxygen sensor my 2003 Honda S2000. With 90,000 miles on the original sensor, the transition from idle to part throttle had become harsh. I used an OBD II adapter to confirm that original sensor had become slow, but not sufficiently slow to cause a check engine light. Installation of the new sensor took under 15 minutes, not counting parking overnight to make sure not to burn myself on the exhaust system.

Fit My 01 S2000 perfectly

Worked perfect on an S2000
