Holley Systemax intake manifold for 5.0 Liter fuel injected 1986-1993 Mustangs.

This is the mother of all intakes! If you are looking to make big power with your small block then this is the intake for you. Features a 75mm throttle body opening and extremely large ports. Has a 2,000 to 6,500 rpm powerband. This manifold works best when used with forced induction like turbos or superchargers but is also compatible with naturally aspirated strokers with high flowing cylinder heads and large camshafts.

Includes upper and lower manifolds, upper to lower gasket, bolt kit and vacuum line fittings. Compatible with all factory style components including fuel injectors, fuel rails, coolant tubes, thermostat housing, and egr spacer although upgraded fuel components are recommended.

Vehicle Fitment

This product will fit the following Mustang years:

Rated 2 out of 5 by from Don't buy unless you can fabricate Don't buy unless you want to fabricate a larger lower manifold baffle as the current is insufficient and will get major oil consumption into your throttle body and intake. Holley has not even noticed the problem although there are hundreds of threads in the forums about the issue. So be prepared to go to open breathers, catch can setup or evac system with this intake.

With your modifications we would not recommend this intake. This manifold works best when used with forced induction like turbos or superchargers but is also compatible with naturally aspirated strokers with high flowing cylinder heads and large camshafts. I would recommend going with the Trick Flow StreetBurner Intake Manifold Kit and a camshaft more suited for that setup.
