TPI Siamesed Runner Identification and Questions
Hey guys and gals, I purchased this TPI Siamesed Runner from a local garage sale but has no name brand on it. They look like SLP but I could be mistaken. Can anyone I.D. per picture?
My questions are:
What are the benefits if this was bolted on solo as is?
What if the plenum was port matched?

SLP for 89-92 TPI. They look like they have already been cleaned up on the ID, too. Match your plenum to them and you'll notice some improvement. Upgrade your intake and you'll notice even more.
