No need to tell insurance... It was on there when you got the car wasnt it????
Easy to fit yourself in about an hour... We have done them at all sorts of places one being a car show last year....
Am running the thermal, you also get another gasket that you fit to help heatsoak, I didnt bother though!
And no, not on commission (Wish I was!!!) , just helping out a buisness that offers great help and an amazing service! Oh and they are great people!!
