NGK 52330 Spark Plug Wire Set, 8-Wire with 2 Coil Leads, Blue Silicone

The NGK 52330 (also referenced as RC-FDZ022) is an 8-wire spark plug wire set with two coil leads, engineered as a direct OE-quality replacement for select late-1970s through early-1990s Ford, Mercury, and Lincoln vehicles. NGK's ultra-low resistance magnetic core wire sets are built to deliver a stronger, more consistent spark while suppressing the electromagnetic and radio frequency interference that can disrupt engine management and in-vehicle electronics. The blue silicone outer jacket and inner EPDM/silicone insulation provide excellent dielectric strength and resist the high heat and chemical exposure found in demanding underhood environments.

Key Features:

• 8-wire set with 2 coil leads — complete replacement kit for the full ignition circuit
• Stainless steel winding over a premium ferrite magnetic (SMag) core delivers ultra-low resistance and a more powerful spark
• Excellent EMI/RFI noise suppression for clean engine operation
• High-temperature blue silicone outer jacket with EPDM/silicone inner insulation — 8.00 mm outside diameter
• Eight angled (135°) silicone spark plug boots glued to cable with silicone sealer for a watertight seal
• Distributor/coil end boots at 90°, black silicone construction
• Stainless steel terminals with up to 3 serrated crimps for maximum terminal retention strength
• Locking C-shaped spring clip with corrosion-resistant plating for a secure, positive spark plug terminal connection
• OE or better specified boots ensure proper fit and durability; specific-fit design (not universal)
• Standard replacement grade; no wire separators included

NGK is a globally recognized ignition specialist with decades of OE manufacturing expertise. The 52330 wire set meets or exceeds original equipment standards and is designed to fit select 1979–1991 Ford, Mercury, and Lincoln models. California Residents: WARNING — Cancer — www.P65Warnings.ca.gov.
