The trans-interceptor, Caspers afpr, and Walbro pump have all at one time served me well at some modding stage.
We didnt have all these mods back in the old days - hence a lot of little products were made it an attempt to go faster. Now, all you need is the basics (pulley, intake, exhaust) and some majors (cam or rockers, headers, intercooler) to be in the high 12's.
MSD red coils are soo much puurtier though. They go very well with red MSD wires too. No problems with both setup compared to stock.
Not everyone will agree with trans cooler being useless.
