The shipping of this O2 sensor extension was amazing! It got here super fast and was in perfect shape. Can't wait to install it.
This sensor signal corrector is a miracle product! It fixed the check - engine light issue effortlessly, and I'm really impressed.
Solved my Tacoma's check engine light! This spacer installed in 5 minutes—perfect 90-degree fit clears all codes. Heavy-duty aluminum withstands off-road abuse. No more CEL since install. Works like OEM at 1/4 dealer price!

Do its job well

Super high quality design and craftsmanship pricey but its worth it trust me

Perfectly fixed the issue of the horn sometimes not working and the warning light staying on all the time.

Beats paying for OEM carburetor

Perfect!

This seller is awesome—their stuff is top-notch. I bought 30 from them before, and only one didn’t work out. I tried another cheaper place and got 50, but at least 15 customers complained they were either useless or failure after a few days. Compared to that, this place is way better. You really get what you pay for. This time, I went all in and grabbed 100—should keep my shop stocked for about two months. Definitely coming back for more when I run out!

Showed up right on time, and the communication was on point the whole way through. 100% would buy again! The grill quality is seriously top-notch.
Highly recommend getting a body shop to install it—there are always little tweaks needed for a perfect fit, especially with the crash bar and sensors. In the UK, you can’t remove the poly padding on the crash bar, so keep that in mind.
Definitely ordering again—looks straight-up classy on the car!

Real solid quality, especially since I couldn’t find it anywhere else. Glad I got my hands on it!

Superb quality. Thanks

The carburetor fit great and started right up. Great buy.

Great carb !!!! Never let me down. Great service from champoo once again. First Class 👍

As good as OEM

My car basically just quit on me—totally stopped moving—and the codes were pointing to an O2 sensor failure. Thankfully, the upstream and downstream O2 sensors I ordered showed up super fast. I bought both just to be safe, but I only needed to swap out the upstream sensor right away (along with some new spark plugs and a MAF sensor I grabbed from another place). After the install, my car’s running smooth again, and that annoying check engine light hasn’t come back. I’ve bought a bunch of parts from 1A Auto before, and honestly, I’ve never had any issues with them. They’ve been solid every time.

My order arrived right on time, no delays at all. I got it installed the very next day, and let me tell you, it fit like a glove! Now I can see everything clearly behind me while I'm riding—no blind spots, no stress. Honestly, I couldn’t be happier with this purchase. It’s exactly what I needed, and it’s made driving so much smoother. Totally worth it!

Fit well and perform well
