DIY – Air filter service on the GTM Stage 1 Supercharger

[wind.zero]

Sam recommends servicing the filters every other oil change, so I have been performing the service every 6k miles. The filters are located in the passenger side bumper where the windshield washer reservoir used to be located. As with all DIY, you are responsible for the safety of yourself and your vehicle. If you are not comfortable or do not have the correct tools, please consult with a shop.

I purchased a new set of K&N filters and put them on. I cleaned the original filters and will re-oil them when it is time to service the filters again. This way, I always have a clean set of filters on hand all of the time. I will probably replace them entirely every year or so. Probably not necessary, but it is peace of mind.

Parts and Tool List

• Floor jack, jack stand, and puck jack adapter
• 2 K&N Filters RC-9350 Filters - GTM AIR FILTER REPLACEMENT TT & SC 2.5" GTM-030-3
• Optional K&N Air filter cleaner and oil if you are reusing the original filters
• 10 mm socket and socket wrench to loosen the clamps on the filters
• 21 mm socket to remove lug nuts
• Lock to remove locking lug nut if applicable
• Torque wrench to torque lug nuts

Step One
Jack up the passenger side and put the car on a jack stand. Remove the wheel for the most room to work. I got some aluminum puck jack adapters from SimTec Motorsports that work safely on the lift points near the front wheels. Remove the passenger side wheel for full access to the fender protector.


Step Two
Remove several pop clips and pull out the fender protector. This is really easy; I think there were 5-7 pop clips. Remove all of the clips and just pull out the fender protector


This is NOT all of the clips but shows the location of several of them. You should get the general idea.


Step Three
Use a 10mm socket to loosen the clamp and pull off the filter. Replace with the new filters or clean and re-oil the original filters. This shot shows the filters and arrows show the clamps.


Step Four
Reinstall the fender protector with the pop clips, put the wheel back on, put the lug nuts back on, lower the car back down, and then torque the lug nuts.

This DIY was designed just to show current and potential GTM Stage 1 supercharger users how easy it is to service the air filters. I hope someone finds this useful.
