Viton O-Ring Set - Lower Intake Manifold, Coolant Passage (12A, 13B 4-Port) [Pair]
$16.00 USD
Pair of Intake Gasket O-Rings.
Being a Viton material allows these O-rings to be reused with confidence and are resilient against Ethylene Glycol, the main chemical in coolant/anti-freeze.
Most OEM and aftermarket replacement O-rings are made of Buna-N (Nitrile Rubber) which deform over time due to normal heat-cycling of the engine. This can become a problem as they will start to lose sealing ability and lead to a coolant leak.
