This would be my third set of Triple 56-1350 K&N Filters as it's my third set of Triple Mikuni 44PHH Sidedraft Carburetors, and the fourth 56-1040 assembly for Weber 38/38s Down Draft carb, they all still look like the day they were purchased. We clean them regularly, which is every four to six weeks with K&N Filter cleaner and oil. Trinidad has a tremendous amount of dust and debris so it is a great test for K&N to be in this environment, and they definitely protect our engines while improving air flow for added power.
We purchase all our equipment from Murray's Speed & Custom in North Miami, Florida.
