FYI, I installed the M7 ones this past weekend. I used a blow drier to warm them up and they went on without much trouble at all. The blue color is a tad light, but otherwise I'm very please with them.

 

I had a possible IC leak when I switched over to the GRS intercooler. I think that the slight change in shape from the stock IC to the aftermarket one caused some slight leaking issues. The Alta boots fixed me right up... plus they gave some nice, cheap, red bling to the engine bay.
