GR86 P0420

I had a check engine light coming on for P0420 on my 2025 GR86 AT, after installing the HKS GT manifold with cat. Was a quick install and once I clear the code, it never came back even when I pushed the car.

Good choice

They're made good with good quality metal. Threads in smooth. I replaced my exhaust manifolds on my 05 mdx with catless resonated manifolds. Threw a code. Bought these, installed, cleared code, drove, no code. Works as advertised.

2018 F150 2.7l O2 sensor spacer worked.

The spacer worked as described. I installed it and didn’t have to reset the check engine light, I drove it around for about 20 mile and the light went off on it own. 2 weeks later and the light is still off and my gas mileage had gone back up the 3 miles per gallon I lost with the 0420 and 0430 code that I had befor the O2 sensor spacer. Would recommend.

Check Engine Light gone

Just installed new headers on my Mustang. Got a check engine light. Put the reader on and it was the O2 sensor. Ordered the sensor spacer on recommendation from the installer and once installed it solved the problem.

90° O2 Oxygen Sensor Spacer Fixed my Nissan

After several trips to the dealer, I finally gave this thing a try and YES... it has been working for my car. No more check engine light on the dash and back to the performance that I'm used to. This has been a success.
