The Roush 3-piece intake. Available on the 94-95 Stage 3 Roush cars, only about 100 (to my knowledge) were built and sold. Roush claimed a 47 hp increase with nothing other than this intake and the "kit" it came with.
Just for scale, that's a 65mm TB sitting next to it (included in the kit).
Crap, look at the lower runners on this thing!
Quotes from the 94-95 Roush sales brochure:
Apply whatever reality modifier you want to the numbers. The actual dyno numbers I've seen are DAMN impressive.
The entire kit included:
3 Piece Intake, Lower, Mid and Upper
Gasket set, (intake, EGR, Throttle Body, IAB)
J4J1 EEC-IV Computer
MAF Extension Harness
IAB adapter plate
65mm Throttle Body
24lb Fuel Injectors
Fuel Rails
Passenger side Valve Cover
New Heater Pipe
Underdrive Crank Pulley
Serpentine Belt
Approximately 4ft of hose cut to different lengths (sizes per manual)
Assorted vacuum fittings
MAF to Throttle Body Hose and clamps
Air box and filter
Fuel Line disconnection tools
Installation Manual
I was able to get it complete, minus the crank pulley. The seller also threw in a Kirbin AFPR and FP gauge for the fuel rail. The original kits from Roush also had an option for the cowl hood (which bumped it to $3000 from $2000
). Unfortunately, it won't fit under the stock hood, so it looks like I'll be getting another one of those before too long.
