News Resources Upgrades FAQ

Make sure this upgrade is compatible with your engine:

What can this upgrade do for you?

Improved reliability when operating on high BTU fuels. With enhanced cooling at the exhaust valve and guide the component temperatures are reduced by up to 40% to reduce stress that can cause unexpected cylinder head failures..
More uptime due to longer intervals between overhauls. Up to 60% longer intervals between top-end overhauls; up to 32,000** hours on L7044 GSI engines operating up to 1,680 BHP @ 1,200 RPM continuously.
Lowered lifecycle costs through lower oil consumption. Series Four pistons feature increased scuff resistance and three-ring design, which can reduce oil consumption by up to 67%, reducing makeup oil cost and catalyst masking.

**Intervals may vary depending on factors such as fuel quality, maintenance practices, and operating conditions. Engine

configuration must be verified for upgrade opportunity.
