Pre-combustion chambers are a low-cost component of an engine. During operation, pre-combustion must endure extreme compression forces and temperatures. With time they tend to crack or become loose, causing serious damage to the cylinder head or the block. CTP offers a full line of replacement Pre-combustion chambers for Caterpillar® applications.
