Honda TRX450R Aluminum Air Box $119.95

All CFM Performance products are proudly MADE IN USA.

New, never installed aluminum air box for the '04 and '05 Honda TRX450R.

Made by CFM Performance.

This air box has an additional 2 inches of clearance between the air box and rear shock. This allows it to work with long travel rear suspension that would hit the stock air box.

This air box is constructed from 5052 series aluminum for highstrength, good looks and excellent corrosion resistance.

This design accepts the stock Honda intake snorkel setup.

Features a bolt on lid with a neoprene rubber gasket.

Run it with or without the lid to suit your riding conditions. 

Does not come with a filter. Works with all filters available for the stock air box.

The stock filter is only 3 1/2" I.D. This air box uses a 4" filter I.D.

Your stock air box has the crank case breather hose attached to it. This air box allows for so much air flow that the crank case breather hose can not be attached to the air box because it can actually suck oil out of your crank case and into the air box. We leave the breather hose open and tie it to the frame in the highest location it will reach. We have run our ATV's with an open breather hose for many years, in all riding conditions with no problems. The crank case maintains positive pressure on the hose making it virtually impossible for anything to get in. The open crank case breather hose has been standard on many ATV's for years. If you would like more protection, you can add a crank case breather filter to the hose.


Honda TRX450R High Flow Exhaust Tip $34.95

New CFM Performance aluminum high flow exhaust tip for the Honda TRX450R. Will fit any year. It comes with a stainless steel spark arrestor screen and stainless steel mounting bolts. The open area of our exhaust tip is over five times greater than the stock piece, which dramatically increases the flow of your exhaust system. More power, better sound and hundreds of dollars cheaper than an aftermarket silencer, the CFM Performance high flow exhaust tip.

This air box uses a 4" filter. The same size as the intake on your stock box. It is a little shorter to allow enough room for your battery, but this has no negative effect on power. You will need to clean the filter a little more often, but that's a small price to pay for the performance advantage.
