Emissions warning light came on, but this fixed it. The adapters did the trick and cleared the issue. I also switched to using mid-grade 89 octane instead of the lowest grade fuel, and since then the emissions warning light hasn’t come back.
After installing the HKS GT manifold with cat, I started getting a check engine light for P0420. Installed this piece, cleared the code once, and it hasn’t come back since — even with spirited driving. Installation was quick and straightforward.
Works great, code has been removed and hasn’t returned
Mind blown. Unlimited constant temperature as long as the engine is running on the highway. 10/10 innovation.
Works perfectly, great seller, good communication, arrived ahead of schedule.
Well made device, works as promised, had a pending code pop up for secondary o2 underperforming, but went away before setting a code.
So far it has worked really well
Great Quality for Price. Working great so far, Passed monitors
Unlike the 1st product that did not clear my p0420 that merely offset my downstream O2 sensor, the Mini Catalizador with the honeycomb like filter was key to eliminating the code altogether. After clearing the code and performing a complete drive cycle, my 2016 CRV past MD emissions.
I track my car and had been fighting codes for the last few weeks. Best money spent issues gone car runs great! I would recommend these to anyone having the same issue. Thanks Rob
2020 Hyundai Tuscon. I live in New York had a P0420 code I used the 45 degree spacer and code went away. I ran it threw the drive cycle 2 days, there went and got Inspection and passed. Would highly recommend.
Had the P0420 CEL, installed the Mini Catalizador on the downstream O2 sensor. After clearing the code drove over 500 miles, the code has not returned. Purchased both short and long 90 degree, had to use the short, not enough room for the long.
Awesome product
I've been having a problem with code p0420 for quite a few years. I installed your product a month ago and finally got my car inspected and have yet to to see the code show back up
fit perfectly and the delivery was good
Very good
So far working as expected. Very happy with my purchase
No CEL, works perfectly
Fixed P420 on my 2012 Jeep Wrangler. Easy to install and worked great.
Great parts and fast shipping
Bought it for my son. He hadn't installed it yet
It will be great if it's what he needs for his car.
Great product easy to install so far no more code issues.
So far so good
Great product,worked on my 2005 Tacoma,no more check engine light.Easy to install and very well made.
Well constructed. Fit perfectly. De-sensitized feedback enough to keep CEL off. I would buy again.
