This gasket kit was perfect for rebuilding my Rancher 350's top end. All gaskets matched perfectly and sealed tightly with no leaks. Quality parts that made the repair straightforward and reliable.

Fixed my charging issue on my Kohler CV491s. The wires were a bit longer than the original but nothing a ziptie didn't fix. Easy to install.
Replace the old one it’s matchable
Can be put into multiple configurations depending on your need. Got rid of the P0430 code I was having.
Fix the P0420 successfuly
Stick on 👍
Great
easy installation
Works flawlessly and simple to install. Just had to modify the bucket a bit by creating a hole on the bottom so the filter sock can be exposed to a good fuel source.
Easy exchange
Adds serious presence to my A7. The hex mesh and black honeycomb scream RS7 style without being overdone. Looks fast, clean, and expensive—love the upgrade.
Solid upgrade for my A3. The RS3 style grille fits without any major issues and the ABS plastic feels durable. It changes the look of the car instantly, very pleased with this purchase.
Looks fantastic on my A4, the RS4 style really suits it. The gloss black and silver chrome ring give it a sharp, sporty look. Fits perfectly and feels solid.
Fits my A4 perfectly and looks fantastic. The gloss black honeycomb really changes the whole front end. Installation was straightforward, just take your time with the clips. Happy with this upgrade.
Fits my A5 perfectly, the honeycomb grille looks aggressive and the black finish is spot on. Installation was simple, just a bit of fiddling to line up. ABS plastic feels solid and overall it really upgrades the front end.
Looks fantastic on my Audi, gives it a real RS6 vibe. The honeycomb grille is well made and the black finish is spot on. Removing the old rings was a bit fiddly, but the end result is worth the effort.
