Installation Overview

Injen states that installation does require some mechanical skills, a qualified mechanic is always recommended, and the system should not be installed while the engine is hot. Injen's instructions include drilling and reshaping the windshield reservoir brace.

• On the reservoir brace, "Drill a 1/4” hole 1” apart from the pre-drilled hole closes to the pivoting point" on the flat end, and flatten the right angle bend with a vice or mallet.
• Move the spacing stud to the reservoir bracket, fit the brace under the air conditioning line with the M6 x M25 bolt and washer, and slip the windshield reservoir tank onto the repositioned brace.
• Screw the vibra-mount between the two pre-tapped holes, press the 2.25" hose over the turbo inlet with two small clamps, and press the stock grommet into the secondary intake.
• Fit the 2.75" hoses to the MAF sensor (tighten the MAFS clamps only), press the assembled MAFS over the primary intake, position the 2.25" end into the turbo hose, and line the secondary intake bracket up to the vibra-mount stud in the resonator hole.
• Reconnect the stock blow-off line to the 3/4" U-pipe with the stock clamp, run the 13"-10mm hose from the crankcase port to the 5/8" nipple, connect the MAFS harness, press the air temp sensor into the grommet, and press the filter onto the intake.
