10 Micron Replacement Filter Element for OMC 502905 from SIERRA
10 Micron Replacement Filter Element for OMC 502905 from SIERRA
High-performance fuel injected engines require ultimate fuel filtration, separation of water from the fuel supply and maximum fuel flow. Sierra’s new filter elements deliver all three of these critical performance factors. 7900-Series 10 micron filters eliminate harmful contaminants at over 90% efficiency, while removing over 99% of emulsified water. Today’s ethanol-blended fuels increase the chances of water in fuel tanks, resulting in premature wear, poor performance and component damage.

Sierra-Tube-Exhaust from SIERRA
Some larger V-8 engines that create a large amount of back pressure use exhaust tubes rather than bellows. This helps to relieve the excessive pressure and eliminate problems with premature bellows failure. In the past, the exhaust bellows would blow up like a balloon and cause the drive shaft bellows to rub against the yoke and U-joints causing holes in the bellows.

Electronic Ignition Conversion Kit, Fits 6-Cylinder Prestolite from SIERRA Home -> Engine Systems -> Engine Parts->High-Performance Electronic Ignition Conversion Kits
They sense the current level in the coil and adjust the dwell to maintain peak energy throughout the entire RPM range. Peak current level is reached just prior to spark, so ignition energy is sustained with less heat buildup, which increases the lifespan of the coil and ignition module. Compared to the non-high performance kits, these develop on average three times more available energy between 3000 & 5000 RPM, and nearly double the available plug voltage.
