  • 180mm
  • 183mm

CNC machined from 6061 T6511 aluminum. Machined surfaces allow for better caliper alignment and a more rigid brake set-up.

The Post Mount standard is universal to the front and rear brakes.

Some frames/forks use a 160mm rotor with no adapter, some use a 180mm with no adapter. Check your frame/fork! Our adapters can be used on both forks and frames with 160mm and 180mm posts. Bumping up from a 203mm post mount (2015–2020 Fox 40 and 49 forks) to a 220 or 223mm rotor is also covered by our adapters.

PICKING THE CORRECT POST MOUNT DISC ADAPTER

  • To go from a 160mm post mount to 203mm rotor you will need a 43mm adapter.
  • To go from a 160mm post mount to 200mm rotor you will need a 40mm adapter.
  • To go from a 160mm post mount to 180mm rotor you will need a 20mm adapter and so on.
  • For 2016+ Fox 36 and 180mm rear brake mounts:
    • You will need the 23mm adapter to work with the 180mm post mount and a 203mm rotor.
  • Going from a 180mm post mount to a 200mm rotor requires the regular 20mm adapter.

The adapters do not come with mounting bolts.

Engine air filters are important!
Size: 8.26" x 5.63" x 2.24"
Just like me and you breathing, your car performs better when it can breathe freely and cleanly. My philosophy with an engine air filter is to replace with cheap and often. You can't control the quality of air coming into your system but you can control the filtering, so I'd rather replace the filter on an accelerated schedule with a cheap product than to invest into something more expensive and have it perform dirty for longer than it should. For my Honda CRV 2024 Hybrid, this filter fits snuggly and performs well.

Two Filters, Quick and Easy
Size: 16-23 Tacoma, Size: 16-23 Tacoma
The RVgolf Engine+Cabin Air Filters Kit for the Toyota Tacoma V6 comes with two air filters. There is a cabin air filter that fits nicely into the compartment accessed through the glove box and an engine air filter that dropped in easily in the compartment under the hood. Replacement of both filters was easy, didn’t require any tools, and it took more time to empty and replace the items in the glove box than it did to replace both filters. The Toyota dealership quoted me $80 to replace the cabin air filter only. I replaced both filters for less than $30. The filters felt like they were good quality. The engine air filter is multi-layered, with a thin foam layer to keep larger debris from blocking the finer paper filter. The cabin air filter said and looked like it had a carbon layer to absorb smells. The only concern I had was size. After I had replaced both filters I went to slide the engine air filter I replaced into the RVgolf box to throw it away. The engine air filter I replaced would not slide into the RVgolf box. It was too big. After driving for a few days and a couple of hundred miles, I popped the hood and checked the fit of the engine air filter. The fit looked perfect. See attached photos.

Fits 2019 accord (gas engine)
Size: 18-22 Accord
Dealer was going to charge almost $200 to change both of these filters in my 2019 accord. These filters fit perfectly and of same quality as the dealer product. Easy to install, saving me lots of money.

Great quality and Easy to install
Size: 18-22 Accord
As someone with zero experience changing air filters, I was honestly surprised at how easy this was. The fit was perfect for my 2010 Honda Accord Sport, and both the cabin and engine air filters installed with no issues at all. It even came with clear, easy-to-follow instructions that made the whole process stress-free. Saved myself money from going to the dealership, and my car is running great. Definitely recommend for beginners wanting to do a simple DIY maintenance job.
