Rod Millen Intake for GTS
By John Unnever

*Included parts
1 - Cone filter
1 - Inlet tube (silver)
1 - Sensor support bracket
1 - stainless washer
2 - 6mm bolts/nuts
2 - 4mm countersunk screws
1 - 13” silver silicon 3/8” hose
1 - 70mm silicon hose
2 - #48 hose clamps
1 - 1/8” vacuum cap
2 - black zip ties

Step 1. Remove the (-) negative terminal from the battery

Step 2. Disconnect the Mass Air Flow Sensor (MAFS) plug


Step 3. On the factory air box there are 2 pressure sensors - one on the upper half of the airbox and one on the lower half of the airbox. Pull the pressure sensor on the upper half of the factory air box off


Step 4. Disconnect the 3/8” hose on the upper half of the factory air box (that is the larger of the 2 hoses)


Step 5. Disconnect the 1/8” hose leading to the Intake plenum (located directly below the throttle cable assembly) and cap with the 1/8” vacuum cap provided


Step 6. Unclasp the 3 clips that hold the factory air box together and undo the 10mm Phillips head hose clamp leading to the upper portion of the airbox


Step 7. Pop off the 3 clips holding on the plastic frame cover in front of the factory air box (covers chassis, between headlights)


Step 8. To remove the lower half of the airbox, remove the fuse box, lower pressure sensor (on lower half of factory air box), and the blue plug (also on lower portion of air box)




Step 9. Re-attach the fuse box. The lower pressure sensor will be re-attached in step 12. The blue plug (vacuum sensor) will no longer beused, as it is eliminated with the RMM air Intake system

Step 10. Remove the rubber inlet tube leading to the throttle body


Step 11. Attach the sensor support bracket to the under side of the bracket that supports the clutch line (using the 6mm hardware). The longest leg of the bracket should be on top and vertical

Step 12. Attach the lower pressure sensor (removed in step #8) to the lower leg using the last of the 6mm hardware


Step 13. Attach the upper pressure sensor (removed in step #2) to the upper leg of the bracket. To attach this pressure sensor, use the Phillips head screw from the factory clip bracket and the washer provided


Step 14. Slide the 70mm black silicon hose onto the throttle body


Step 15. Remove the MAFS from the upper portion of the factory air box. Relocate the MAFS into the RMM inlet tube using the 4mm hardware provided (tighten evenly!!)


Step 16. Remove the factory rubber hose from the lower pressure sensor. Attach the 13 x 3/8” silver silicon hose provided


Step 17. Install the inlet tube and plug in the Air Flow Meter Sensor. The sensor is now located next to the throttle body (check this to make sure the inlet tube is oriented correctly)


Step 18. Slide on the air filter and attach the silicon hose to the nipple on the air filter


Step 19. Tighten the hose clamp allowing a gap of approximately 1/2” between the air filter and the radiator fan shroud

20. Attach the (-) negative battery terminal
