The greddy type-s is slightly more expensive then the type-r. I use the type-s with great results and purge it to the atmosphere. The type s has a high pitched chirping sound kinda sounds like a WRC rally car. It is very loud!
The type r sounds like air venting..kinda sounds like a big bus stopping and opening the doors like a woooosh sound.
The type s is more distinct and I know for sure works with our MAF sensors.
