    Very good filter

    Decided to try out this new filter in my 08 CRF450R. Went in easy, much less restrictive than the OEM filter. I loved the included wing nut with the plastic grip on it. It was a little tight getting in the Honda airbox, but not as bad as the OEM filter and mesh cage is. Overall, I am very pleased with this filter. I haven't had to clean it yet, but no filter is fun to clean. Also, so far I have not had to make any carb adjustments. I ride at between 1200-2200 ft.

  • Twin Air Billet Air Filter Bolt

    Twin Air Billet Air Filter Bolt

    Russ in TX

    AMAZING!

    I was skeptical or dropping $$ on a screw. I could care less about the looks of this particular part as no one will ever see it! But I absolutely despise my CRF250X when I have to put the air filter back in - sometimes taking up to 5 minutes!! When i openened up the twin air package and compared the bolt to the OEM one, it really isn't much longer and I was pretty skeptical. However, when I went to install the air filter it was amazing how easy it lined right up!!! I've done 4 or 5 filter changes with this bolt now and every single time the bolt magically goes right to it's hole and I'm done in 15 seconds!!! You won't regret this purchase.

  • Dragonfire Racing FireBreather Intake System

    Dragonfire Racing FireBreather Intake System

    Derek in CO

    Kind of a pain

    I just installed this on my 2013 RZR XP LE. Its unfortunate that cutting into the rear of the bed is a must. It's fairly easy install, a roto zip would make it even easier to cut. As for the details in the instructions, I would give it a 8 out of 10. The oil breather was vague as to the best location but I routed mine up to were the original intake is at and trimmed the black pre filter a bit so you cant even see it but secure with a zip tie and easy to access. Looks pretty cool and seems to reduce the intake restriction but allows more air to enter into the motor. Oh and I suggest taking out the old intake system so you can route the oil breather up, its easy to remove.
