NGK – Ignition Wire Set (Part No.F1020268445NGK)

Ignition Wire Set

from

$70.83
NGK Resistor Spark Plug Wire Sets utilize a construction method known as variable pitch wire winding to create resistance to radio frequency interference. The variable pitch winding (loose/tight/loose) provides suppression throughout a very wide range by scrambling and breaking up the electrical waves radiated by the firing of the spark plugs. A ferrite magnetic layer consisting of a mixture of rubber, plastic and powdered ferrite magnetic materials, offers uniform resistance and unsurpassed conductivity. NGK wires have a lower resistance than conventional carbon core wires (8k ohm/meter versus 16k ohm/meter). This comparison is important to remember when you consider that many manufacturers recommend wires be replaced when the resistance exceeds 20k ohm/meter. This does not leave much margin for wear when the wire may only meet original standards at the very early stages of its life.

Product Features:
  • OE-Equivalent.
  • OEM style connectors for easy Installation.
  • Superior Firing and Fuel Savings
  • Outstanding Durability and Performance
  • Excellent Noise Suppression
  • Numbered for easy cylinder identification.
  • High quality EPDM and Silicone coverings.

Nippon Reinz – Spark Plug tube Seal (Part No.A8027177121NRZ)

Spark Plug tube Seal

from

$6.30
Nippon Reinz Spark Plug tube Seal withstands high and low temperatures to provide a reliable seal with minimal tightening. Spark Plug tube Seals are increasingly produced with profiles and not flat; that is, the gasket surface is provided with beads or lips. Now, instead of the entire gasket surface, only the profile needs to be pressed, that is, the sealing bead or sealing lip, and just a slight amount of bolting force produces sufficient deformation and adaptation.

Product Features:
  • Stays cool at temperature up to 1800F
  • Designed to seal minor surface irregularities
  • No re-torque required
  • Teflon® coating optional
