My granite 2014 srt8's black motor is kinda bland. Was looking to shine it up a bit. Im interested in something ive seen.There stainless steel 392 HEMI fuel rail cover overlays. Looks like they go over existing covers. Has anyone put them on. Are they any good ? Searched many forums and havent seen anyone with these on there car or any talk of them. Also any other recomendations would be appreciated. Thanks guys.
