The 69-8703TS has a mount for the factory mass air sensor. Simply remove it from the stock air box and install it into the K&N free flowing mandrel bent aluminum intake tube, securing it with the provided hardware.

The 69-8703TS is designed to reduce restriction and provide the benefits of a washable and reusable lifetime replacement K&N air filter (RT-4590).  This K&N cone shaped air filter has a titanium top for added strength and light weight.

The manufacturer’s air box restricts air flow to the engine. K&N performance air intake systems provide an increase in power while providing excellent filtration. The K&N air filter is protected by a heat shield assembly which fits into the engine compartment and allows the K&N air filter to receive a consistent flow of fresh air.

Our K&N air intake systems are designed to be installed in 90 minutes or less and are backed by the famous K&N Million Mile Limited Warranty.
