  Gasket Spark Plug Pipe

• Description:

  A spark plug tube seal (10966AA030) prevents engine oil from entering into the spark plug and accumulating on the equipment’s bottom part. The unit has a circular design and features top-grade materials that can withstand extreme pressure and high-voltage electricity. Moreover, it is important to choose a compatible cover for your Subaru vehicle’s spark plug.

  Without a tube pipe, the oil from the valve covers can travel down to the spark plug’s interior parts, inhibiting its performance. This issue will have adverse effects on your engine and ignition system. Hence, it is essential to regularly check if the tube cover is securely attached to the spark plug.

  With the use of a genuine spark plug tube seal, you can avoid costly engine and ignition system repairs. However, it is not enough to install aftermarket equipment. You should attach an OEM tube pipe to prevent further damage to your vehicle.
