All MaxSil™ Pistons for BMWs are warranted against defects in material or workmanship
for a period of 5 years (unlimited mileage) from the installation date.
If a defect is ever found, a new set of MaxSil™ Pistons (with new rings) will be
sent by next day air freight at no charge.
Overheating, turbocharging, supercharging, improper installation, and/or running
without proper lubrication voids the warranty. Running the engine for prolonged periods
with an improper fuel-air mixture (too rich or too lean) also voids the warranty.
The MaxSil™ Piston warranty is limited to replacement of pistons and shipping only.
No other costs or expenses incurred by the distributor, installer, or their customer
will be provided.
All Maxsil™ Pistons are re-inspected and all critical tolerances re-measured prior
