Land rover Defender  MUD Puma Heater Deflector solves the problem of that crude and annoying blast of hot air to your lower legs in all Puma engine Defenders  (2007 onwards, 2/2.4Tdci). The PHD 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 PHD moulding fixes easily in place using the supplied push-fit fasteners and can be fitted in 5-minutes (see fitting instructions tab above).All you need is a 4.5mm drill. Position the PHD. Drill the fixing holes in the lower dash section and fix the PHD in place using the push-fit fasteners.
