Great job on expediting the right product in a timely fashion. Very easy install. If/when you have specials (specifically oil filters for a 3.2 L Porsche Cayenne) notify me. BTW: my onboard computrer suggests I have increased my gas milage by 3 MPG.

Very prompt dispatch and delivery. Five days after installation (quite simple even for a RR TDV8) I am recording a 3 mpg improvement on my trip recorder @ motorway cruising speed, that equates to a 10 saving in fuel costs. I'm thrilled! It has probably paid for itself already. Pity I can't get the emissions rating re-assessed to reduce the 515 quid annual tax penalty.
