Keep Your Late-Model GM at the Head of the Pack with ZZPerformance Parts and Accessories

ZZPerformance is the go-to source for hi-po gear for late-model GM 3800, Ecotec, and LS engines. The company designs, tests, and manufactures all their products in house to keep costs low and quality high, passing the savings and performance on to you. 

High-Voltage Coil Packs
ZZPerformance’s High-Voltage Coil Packs have improved core material and tighter coil windings for a stronger spark. That increased spark energy leads to quicker starts, smoother idling, better fuel economy, drivability, and high-RPM power.

ZZPerformance’s High-Voltage Coil Packs are available for 1999-2019 GM LS with square-style coils, 1992-2009 L26, L32, L36, and L67 GM 3800 V6 engines, and 2011-16 GM 1.4L engines.

Exhaust Insert Cones
Bring down your exhaust volume without the need for extra resonators or mufflers with ZZPerformance Exhaust Insert Cones. Features include:

• 1 to 3 dB noise reduction
• T-304 stainless steel construction
• Little to no power loss
• Weighs less than 1/2-pound each
• Compact size fits all racing applications

ZZPerformance Exhaust Insert Cones are available to fit 2.5- and 3-inch pipes. They can be held in place using an integrated nut or by tack welding them in place. 

Nose Drive Couplers
Don’t be fooled into replacing your entire blower assembly when you hear a rattling noise at idle that goes away when you rev the engine. In all likelihood, all that’s bad is the nose drive coupler.

ZZPerformance Nose Drive Couplers are made from a proprietary oil-impregnated material for less friction than a standard supercharger coupler. They’ll eliminate the annoying idle rattle and they’re purposely over-engineered to provide years of trouble-free service, especially on cars with smaller-than-stock supercharger pulleys.

ZZPerformance Nose Drive Couplers fit most 1990-present GM brand and Eaton M62, M90, and M112 superchargers.

Summit Racing also carries ZZPerformance upgrade mufflers for Chevy Cobalt SS and Saturn Ion Redline, bypass valves for Eaton M90 superchargers, and universal-fit exhaust resonators.
