LPG Variants
LPG with non sequential LPG injection systems. (best 1994 through 1999)
Thissystem was ultimately designed for such simple and effective systems& offers initial resistance to throttle for perfect crisp throttleresponse even on a cold engine as well as the power and efficiencygained from the use of a KN free flow filter that offers superb higherRPM power consistency.

LPG with Sequential injection systems.
(essential 1999 through 2003)
Hereit is also important to have good clean air flow at higher RPM so thissystem will also offer substantial improvements, better still you willnot need the power shroud making what you need at a cost of half ofwhat you see listed here
