Cylinder

Since 1950
Assembly NEW &

Laser Sales' new line of premium cylinders are engineered and
manufactured to provide optimum performance. IMPROVED!

This premium Nikasil coating process which employs
scatterplot & pore type nanoscale electric ceramic
sedimentation, gives firm sedimentary film on the cylinder bore.

Evenly distributed micropores on the bore surface improve
lubrication, heat dissipation and heat usage.

Cylinder blocks are machined from a light-weight
aluminum alloy with a heat dissipation performance
42% higher than metal, with the additional benefit of
reducing overall engine weight.

Benefits Include:
• Extended engine life
• Reduction in fuel consumption (up to 15%)
• 50% reduction in cylinder pollutant's
• Improved performance with better acceleration
• Increase lubrication in cylinder bore

THE "POP UP" Cylinder- this offering features a specific type of
More Models piston design where the center section of the piston is raised,
in the LASER creating a higher compression ratio within the combustion
catalog NOW chamber when it moves upwards, resulting in increased power &
AVAILABLE! torque from the engine; essentially, it's a piston with a "pop-up"
center section that compressed the fuel mixture more
efficiently than a standard flat -top piston.
