I've been looking at old threads and wanted the Outlaw Engineering ThermoBlok spacers, but the website that was linked doesn't exist anymore... Anyone know where I could get these or something similar? New to this so I don't know trustworthy websites, etc. (PS. I have a 2003 Acura tl-s with 195k miles)

 

you can use a P2R manifold spacer or even the stock MDX spacer.
it will impede your hood clearance, you will need to modify your hood...by either cutting out the bracing, or spacing out the hood...or even both
