Product Details

Dragon PCV Breather (818-111-101) by Weapon-R®. The Polyurethane foam in the Dragon air filter flows more air and traps more dirt than comparable paper and cotton filters. The Dragon air filter is one of the highest rated air filters in the world.


Finish: Chrome


  • Polyurethane foam flows more air and traps more dirt than conventional filters
  • Disassembles easily for cleaning
  • No oiling required
  • All Weapon-R foam air filters are backed by the Weapon-R Million Mile warranty

A high performance air filter should flow the maximum amount of air but still provide adequate filtration. Studies have shown that the Polyurethane foam used in Weapon-R Dragon air filters flows up to 80% more air and has better dirt filtration than conventional cotton filters. The Dragon air filter also features an internal tuned velocity stack, technology derived from Weapon-R’s Secret Weapon air filter, for even more airflow.

The Dragon air filter disassembles easily for cleaning, and cleaning is easy because the filter element never needs oiling. The Dragon air filter is available in 3-inch and 4-inch inlet sizes and a choice of various colors. All Weapon-R foam air filters are backed by the Weapon-R Million Mile warranty.

The Dragon air filter is durable enough to withstand many cleanings. To make your filter as good as new, Weapon-R recommends cleaning the filter with Weapon-R’s Foam Air Filter Recharge Kit. Simply remove the mounting screws and disassemble the filter. Spray the cleaning solution on the outside of the air filter. Soak/spray water on the outside of the filter and allow it to sit for 30 minutes. Rinse the filter in lukewarm water. Shake off the excess water and let the air filter dry.

Weapon-R® Dragon Filter Heat Shield. Complete your filter installation with the Dragon Filter Heat Shield. This Shield bolts directly to the top of the Dragon filter and completely shields the filter from any heat to create additional horsepower. You can also attach the hose from the Ram Air Kit to the top of the shield. The Dragon Filter Heat Shield is made from heat resistant plastic to help resist heat soak.

All products are carefully designed using the latest computer simulation and modeling techniques, followed by extensive dyno testing.

I put the breather on my Forester and it looks really good; my engine seems to be running a little better. It has better response and it just runs smoother. I'd recommend this part to any and all my friends.

Breather Fliter
Throttle response is great... Little faster off the line. Def worth the change to get one with the Dragon Cold Air Intake.

Weapon-R Dragon Filter Breather
I bought this product for my 96 Eivic Ex. The product work well is easy to install, it does come with some instructions on it but it's hard to see what they are showing in the picture. Overall, the product works as intended.
