The K&N KT-6908 is a washable, reusable panel air filter built on K&N's oiled cotton-gauze element, made to replace the stock filter in the factory air box of the KTM 690 SMC and Enduro R. The manufacturer describes it as a high-flow upgrade that aims to add horsepower while keeping filtration intact. Rather than buying a disposable element at every service, you clean and re-oil this one. The manufacturer says it only needs cleaning about every 50,000 miles of normal highway riding.
Fitment is the first thing to check. The manufacturer lists the KTM 690 SMC and Enduro R for 2008 through 2019, while its model-specific category pages show 2008 to 2011 Enduro and SMC applications, so the covered years vary by model. Confirm your bike's year with the manufacturer before ordering. For DIY owners, the manufacturer says the panel is engineered to fit into the factory air box, and it lists a re-oiling amount of 0.58 oz (17 ml). The manufacturer also states the filter is emissions legal in all 50 states.
