I ordered an intercooler and upper charge pipe for my N55 F15. I also ordered the $10 stencil and the $15 o-ring for the charge pipe, the stencil was tossed in the box with the rest of the intercooler and a portion of the "F" got bent and had to be taped down while painting, this should have at least had it's own cardboard sleeve or some sort of protection during shipping. It would have been nice to know whether or not the o-ring was necessary, I decided to order it for an additional $15 and I'm glad that I did because it didn't come with one which is pretty ridiculous for a $210 pipe. The install wasn't horrible but I had to alter my radiator fan housing with a dremel which wasn't too bad but this doesn't fit with out the modification and there were no instructions included. The performance seems to be good, I won't know until I order the downpipe and get it tuned. I'd say I'm overall happy with my purchase but was disappointed with the things mentioned above.
