When installing Poison Spyder DeFender XC's, the Inner Fender kit provides splash protection to the engine compartment as well as a place to mount under-hood accessories. Each inner fender is a 3-piece bolt-together assembly, made of CNC laser cut aluminum sheet. Please note that no accessory mounting holes or brackets are provided, as each installation is left to the discretion of the installer to decide where to mount components. Most stock inner fender-mounted components can be re-mounted to the DeFender XC Inner Fenders by simply drilling a hole and/or fabricating a simple bracket. Unfortunately, we have not yet found an elegant solution for retaining the stock air box, so an aftermarket air intake or open air filter element (such as a K&N conical filter) is recommended. The part number for this item is Poison Spyder 14-02-099 and it fits 1997-2006 Jeep Wrangler TJ models.
