Or it also depends on the dealer, and Ford Tech. Some it will not bother, while others will void your warranty. Just talk to your local dealer. Cost nothing to find out.

When you install Ford Racing parts the engine warranty then gets handled with Ford Racing instead of FOC. From what I hear they can be a real pain to deal with too. Its probably still best to go that route or someone like Roush as they also carry a warranty.
