I changed over this week. I had no choice since fitting my new suspension and the addition of the 2.4 manifold and T/B. I'm paying a bit more than what I was before but with the amount of mods i've got i'm not complaining.
Didnt work for me last year, they were £60 dearer without declaring the mods over Hyperformance.
Incidently Hyperformance was the only company i could find 11 years ago to insure my modded XR4X4 V6 Cologne 2.8 with monster Garrett turbo as 'unlimited horsepower' at a reasonable cost as well.
Wheels, sound declared as well, the comment is the replace with factory priced stuff, so well in.
