Focus RS Performance
Going to keep this short-ish, wanted to post because I haven't seen any real / good reviews of it anywhere online.
Pros:
Works great - 2500-6500 RPM 3rd gear in 79F ambient, charge temp dropped to 81F and climbs to 86F for 7F delta at 6500 RPM
Fitment is great, no complaints.
Thick - 24x8.5x5...
