ATI Super Damper standard harmonic balancers are specifically designed for high-rpm engines. Their proven elastomer is designed and tuned to eliminate harmful crankshaft harmonics that cause parasitic horsepower loss. They are actually two dampers in one--a 4 in. diameter inner damper and a 6 3/8 in., 7 in., or 8 in. diameter outer damper in two shells that bolt to the crank hub. These dampers are engineered to all but eliminate worn parts and timing problems. They're tunable in the field, rebuildable, and extremely efficient at all rpm.

Honda K-series (K20A/A2/A3/Z1/Z3 & K24Ax)

ATI Performance Products has developed Super Dampers for the new Honda K-series engine for ‘02 Honda Civic Si & Acura RSX for both street and racing applications. The street version (Part # 918477) comes with 360° laser-etched timing marks and features a single serpentine belt drive on the outershell to utilize the factory serpentine belt set-up. Race dampers allow for the mounting of a dry sump oiling drive gear to the front of the pulley. All K-series Super Dampers exceed SFI 18.1 Safety Certification and are approved for NHRA & IHRA competition. 

Total weight (2-ring): 3.75lbs / Inertia weight: 2.20lbs
Total weight (3-ring): 3.60lbs / Inertia weight: 2.20lbs

Installation Note: ATI dampers are a 1-thousandths press fit, they do not just slide on like OEM crank pulley. They will need to be pressed onto the crank snout with a damper install kit.

Weird Smell
Good for but the carbon has a weird smell. I have a sensitive nose and I'm not a fan. Going to replace with a regular filter without the activated carbon.
