NGK 55005 spark plug wire set for the 2004-2005 Subaru Outback H4 2.5L and other vehicles carries high voltage from the ignition coil to the spark plugs. Each NGK wire keeps that voltage inside its insulation so the spark fires at the plug instead of arcing to ground.
- Mag core construction: stainless steel winding over a ferrite magnetic core for ultra-low resistance and EMI/RFI noise suppression
- Silicone outer jacket built to withstand temperatures greater than 250 degrees C
- Inner insulation of EPDM or silicone contains high voltage current for dielectric strength
- Spark plug boots glued to the cable with a silicone sealer for a watertight seal
- Stainless steel terminals with up to 3 serrated crimps that bite into the cable jacket and inner insulation, where possible
- Locking C-shaped spring clip with corrosion-resistant plating for a secure spark plug terminal connection
Quick facts
- Part: NGK 55005 spark plug wire set
- Fits: 2004-2005 Subaru Outback H4 2.5L and other vehicles
- Material: silicone outer jacket with EPDM or silicone inner insulation
A worn spark plug wire set can show up as a misfire, a rough idle or a check engine light. A spark plug or the ignition coil can be behind those signs too, so start with the engine off and cool: look along each wire and boot for cracks, burn marks or corroded terminals.
