K&N 33-2788 Air Filter Product Reviews

Tuesday, September 25, 2018 - Part 33-2788
Perfect fit as expected. The major advantage I can see without any modifications is that the filter only fills less than 1/3 of my standard air box. The air box gets its air form a tube from the fender well. The tube extends into the air box and is open on the bottom so any water that has made it that far is dumped in the bottom to be drained by a hole in the bottom. So a thinner more efficient filter allows space for a greater volume of air in the box. Giving the air time to slow down drop any water, dirt, bugs,heavy stuff also now my engine has a greater supply of air available to pull into the filter and into the engine. My stock system that was engineered has been improved in 10 minutes. With a 2.5 ton dog every little bit helps.😀
