LAND ROVER DEFENDER MUD Puma Heater Deflector The MUD Heater Deflector solves the problem of that crude and annoying blast of hot air that bakes your legs and handbrake lever in all Puma engine Defenders. The Heater Deflector redirects the flow of air from the lower heater outlets forwards into the footwell, rather than directly at your legs to create a more comfortable driving environment. The Heater Deflector moulding fixes easily in place using the supplied push-fit fasteners and can be fitted in 5-minutes. All you need is a 4.5mm drill. Position the Heater Deflector, drill the fixing holes in the lower dash section and fix the Heater Deflector in place using the push-fit fasteners. This corresponds to the following part numbers: MUD-0020, DA4599 This will fit the following vehicles: Land.
