Pack of 8 thermal insulating socks designed to provide effective protection for spark plugs and spark plug wires in V8 engines, when these are close to the exhaust manifold.
Essential on LS / LSX engines subjected to high temperatures.
On many V8 engines (particularly American LS / LSX type V8 engines), the spark plugs and ignition cables are very close to the manifolds.
This often results in
- hardening/melting of spark plug wires
- cracked insulation
- misfiring when hot
- recurrent breakdowns in sports use
These thermal protection socks are slipped directly over :
- the spark plug
- the spark plug wire
They create an effective insulating barrier against :
- radiant heat from the manifolds
- thermal peaks in the engine compartment
- hot zones in track / drag / drift use
Thanks to their woven fibreglass design, they offer excellent thermal resistance, while remaining flexible and easy to install.
➡️ The kit is sold in packs of 8, ideal for fitting to a complete V8 engine.
