Reviving an old thread.
If I’m reading the last post correctly, the cleaner spray passes through them the IC, through the turbo, then the throttle body. Anyone else tried this maintenance yet?
Did you notice your car running, starting, idling or accelerating better? Quieter valve activity? After the treatment.I used the CRC GDIV intake valve cleaner on my car just a few weeks ago. I only had 12k miles and no scope to check the before and after. Its not going to take years and years of carbon buildup off however it should do great as a preventative maintenence treatment. I plan on doing this twice a year. Its not expensive and it will keep the buildup to a minimum.
As far as use it was easy I simply loosened the cold side pipe from the factory IC to the throttle body enough to get the spray nozzle in right before the throttle plate. I enlisted my gfs assistance to hold the gas steady as I emptied the can into the intake. It's a lengthy process at least 15 to 30 minutes to empty the can.
I also found another similar product at autozone that was touted as specifically for direct injected motors.
