Id say save your money on the engine bling as its only all worth it if you have all of it, not just one part. As for the gaitors ive got the same colour interior as you and i got black with black stitching as nothing else has stitching that is a different colour, to give u abit of an idea heres mine

If you want a better picture im working on the car all day tomorrow so i can take one or two for you then.
