Dobinsons 4x4 Snorkel kits offer a high quality Raised Air Intake System. Offering a great solution to provide cleaner air to the vehicle’s engine. SN59-3461 is designed specifically for the body and OEM air intake of the 2015 Toyota Tacoma with a 4.0L V6 gas engine. I put It in my 2.7L without any modifications. Rotationally molded using precision CNC shaped aluminum dies, this ensures proper vehicle fitment every time using the supplied instructions. The Snorkel kit increases the air intake height to allow safer water crossings and reduce dust intake, and after following the installation instructions carefully, your snorkel kit could seal out excess dust and moisture from your air cleaner. The increased air intake height rams cooler, cleaner air into the engine performance due to a cleaner air filter with more free flowing air. I also replaced my air filter with a K&N filter in the inlet box. I also added the Sy-Klone Series 9001 Air Precleaner for the inlet. This was my second major improvement that I installed.
