Carter Y. ★★★★★ Oct 22, 2026

Installed this on my K20A3 and the check engine light finally turned off. The pigtail wiring made splicing into the harness straightforward.

Eli Z. ★★★★★ Oct 21, 2026

I was a bit nervous about replacing my knock sensor, but this plug-and-play pigtail setup made the job almost too easy. The connector clicked right into place on my K20, and the car's been running smooth with no check engine light. Saved a good chunk compared to the dealer quote.

The pigtail wiring was exactly what I needed to avoid a whole new harness, and the fit on my K20A3 was spot on. Fixed the knock sensor error and the car runs way smoother now.
