E3® SPARK PLUGS WITH DIAMONDFIRE™ 
TECHNOLOGY DELIVERS OPTIMAL PERFORMANCE
The unique geometry of the E3 design provides optimized spark paths well into the useful life of the spark plug, having long-term effects on engine performance.
Only E3 spark plugs feature a diamond-shaped electrode with a revolutionary Edge-to-Edge design. DiamondFIRE technology, proprietary to E3 Spark Plugs, allows the fastest flame-front to grow unimpeded towards the piston to create a more complete burn of the fuel/air mixture in the cylinder.

“HOLLOW STEM” STAINLESS STEEL VALVES INTRODUCED BY MANLEY
The primary advantage of the hollow stem design is a reduction in overall valve weight —which is important for engine builders seeking optimum performance. It’s ideally suited for those applications where budgetary constraints or rule limitations preclude the use of titanium valves.
Small block and big block Chevy, plus Gen II custom-sized hollow stem valves are in Manley’s industry-leading Severe Duty® family, featuring high heat NK-844 material specs.

DREAM CORVETTES GET SUPREME GAS MILEAGE WITH THE FITCH® FUEL CATALYST
The Fitch Fuel Catalyst is a unique in-line fuel system that reformulates and resuscitates 
fuel. Unlike fuel additives, the Fitch Fuel catalyst is a permanent answer to increased gas mileage. As fuel flows through the Fitch Fuel Catalyst the fuel is reformulated to a condition capable of a more complete combustion. The engine then converts the chemical energy in the fuel to mechanical energy in a more efficient manner, increasing engine power, gas mileage, and reducing toxic emissions significantly.
To view information, lab results, or to order a Fitch Fuel Catalyst, visit www.fitchfuelcatalyst.com.
