Good to see/know. However, don't read TOO much wiggle room into some of the wording. The FTC defined "aftermarket" VERY loosely. I would not assume that THEIR understanding of "aftermarket" is the same as an enthusiast's definition. THEIR aftermarket seems to read non-OEM, where OUR definition might include high performance. Example; A bigger turbo is certainly aftermarket, but probably does not fulfill the intent of the FTC's wording. As for Honda's wording, there may be an implication of warranty issues, but they did NOT say that.
