Effective and Easy to Install

Based on my experience, this clamp air filter provided noticeable improvements in my car's performance. It was also a breeze to install - even for someone with limited car knowledge. The high-quality materials used in the filter made it durable and long-lasting. However, the filter was slightly pricier compared to other options in the market.

Pros
  • Easy to install and use for improving air quality in vehicles.
Cons
  • May require frequent cleaning and maintenance to ensure optimal performance.

Big/great filter on filters

I got one of these from Walsh RaceCraft, bought an old Ltr450 Pro Race quad and they put it in their intake kit. This is the largest filter you can fit on an LTR450 and can be just over a finger's breadth from the exhaust pipe. He is tall! Anyway, I messed up a filter in an accident and couldn't find that filter. Luckily I was able to find the real part number and buy Revain pretty cheap. I will definitely buy more of these

Pros
  • NO PROBLEM WARRANTY: 1 year limited warranty
Cons
  • little things

Perfect replacement for my Densecharger CAI Air Filter

Attempted to find a new air filter for my CAI filter old and deformed. I couldn't find a matching part number for my old filter, they only had F045A6 on the base next to the clip and B050A6 on the top. After hours of searching the internet I came across this filter. I read the dimensions in the description, pulled out a tape measure and measured the dimensions on my old filter. They seemed close enough that I bought this air filter and when it arrived it was PERFECT. I don't know if you're also

Pros
  • K&N Filter lasts longer than 10 disposable filters.
Cons
  • Low repairability
