i have seen black and light gray factory LS1 intakes, any correspondence to years with color diff? any differences otherwise?

 

its called rattle can!

 

i know they can be painted, but although most are black that i have seen- i have seen a few that seem to be a crappy light gray color that appears to be more of a well worn factory finish than a spray job.

 

the stock ones are all black. the light gray ones are aftermarket, FAST brand intakes

 

or possiby uv faded......

 

No, it doesn't go solid grey. He's seeing the FAST intake or a spray can mod. Weiand makes an aluminum intake with natural metal color.

The FAST 90 and 92 is still worth $600 or more used. I think there might have been a smaller version (FAST 78 ??) in the early days but wouldn't think it is worth anything now.
