Customer Reviews
Great fit
Test pipes solid but doesn’t line up 100%, need to do some modification on it.
Great quality for the money. Welds are great and packaging was great. Shipping caused the outer box to be quite damaged but the product was perfect. I would order again in a heartbeat! No brainer!!
Looks nice, decent quality, and easy install
This replace the original piece and was made even better.
Let customers speak for us
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
This product is awesome! Shipping was super fast, and the build quality of the front grille is top-notch. Installation was way easier than I thought it would be—even though some videos and forums made it seem complicated, it’s totally DIY-friendly. Every clip snapped right into place, and the final look is stunning. I’d highly recommend tackling this yourself!
I was having a surging issue, and it would falter under load. I tried running Sea Foam through it three times, which helped a little, but it still wasn’t running right. Then I bought a cheap replacement carburetor from another vendor, but when I installed it, it was a complete no-go.
Finally, I decided to invest in this Onan carburetor, and the generator fired up immediately and now purrs like a dream. My advice? Spend the extra money on an original manufacturer’s part—it’ll save you a ton of hassle in the long run!
When I first installed it, the check engine light was still on, and I was like, "Oh no, did I just waste my time?" But then, after driving just a little bit, the light went off—like magic! And dude, my car feels like it’s got way more power now. It’s been about 300 miles since then, and that light hasn’t come back on. Fingers crossed it stays that way for a long time. This thing’s been a game-changer for my ride!
Yo, my catalytic converter was straight-up ancient, and that dang check engine light had been on for months. It was driving me nuts! Then my buddy told me this site could hook me up. I figured, why not give it a shot? So I placed an order, and boom—problem solved! This site’s legit, no cap. 🙌
This grill totally amps up the sporty vibe of my ride while adding a sleek, classy touch with its glossy finish. The honeycomb mesh design is sharp and gives the car a meaner, more aggressive look. Putting it on was super easy, and the quality is legit top-tier. If you’re thinking about upgrading your grill, this one’s a no-brainer—highly recommend!
What really sets this top-end rebuild kit apart is how efficient it is. It’s designed to cut down on the time and effort needed for a rebuild, saving you both money and headaches down the road. Plus, it includes clear, easy-to-follow instructions that make installation a breeze.
