Chevy Small Block 8.5mm Black Ignition Wires with 90° Ceramic Plug Boots

• Spiral-wound Kevlar® core reduces RFI while maintaining spark delivery

• High-density silicone jacket with ceramic boots resists underhood heat

• 90° boots for clean routing — verify your distributor/coil layout first

• Fits Chevy Small Block Gen I; full set of 8 plug wires + 1 coil wire

Refresh your Chevy small block ignition system with this 8.5mm spark plug wire set, built for clean routing, stable spark delivery, and long-term heat resistance in tight engine bay layouts. The spiral-wound Kevlar® core helps transfer spark energy while reducing electrical interference, with resistance rated at 500 ohms/ft — confirm this matches your ignition system's requirements.

High-density silicone insulation and black ceramic plug boots are built to handle elevated underhood heat, supporting routing near warm engine components when installed with proper clearance. This set uses a 90° spark plug boot configuration — confirm this matches your distributor or coil pack layout before ordering, since straight or 45° boots may be required for some setups.

Applications
Fits Chevrolet Small Block V8 Gen I: 4.3L/262, 4.3L/265, 4.4L/267, 4.6L/283, 4.9L/302, 5.0L/305, 5.0L/307, 5.4L/327, 5.7L/350, 6.6L/400 in³. Common on Camaro, Chevelle, Nova, C10, and El Camino small block applications.

Installation
Confirm spark plug terminal style, coil or distributor configuration, cylinder routing order, separator placement, and heat clearance before installation. Verify 90° boot configuration matches your setup — straight or 45° boots may be needed for some layouts.

What's the difference between this set and TSP's "Over Valve Covers" or "Under Header" wire sets?
This set does not specify a particular routing style. TSP also offers routing-specific wire sets for over-valve-cover and under-header installations. Choose the version that best matches your engine's required wire lengths and routing path.

Will 90° boots work with my distributor?
Verify your distributor or coil terminal orientation before ordering. The 90° boots work well with many configurations, but your specific layout may require a different boot angle.

What's the resistance rating on these wires?
500 ohms per foot. Verify that this resistance is compatible with your ignition system requirements.

How many wires are included?
The set includes 8 spark plug wires plus 1 coil wire.

Will these wires handle heat near my headers?
The high-density silicone jacketing and ceramic boots are designed to withstand elevated underhood temperatures. Proper clearance from direct or extreme header heat is still recommended.

What material is the wire core?
Spiral-wound Kevlar® core with RFI suppression.
