Questions & Answers
Is this a genuine original part?
This is a premium quality Recmar aftermarket replacement part, manufactured to meet or exceed original equipment (OE) standards for conductivity and insulation.
How do I know if it is compatible?
This kit is specifically for V8 engines with the Delco EST (Electronic Spark Timing) distributor. If your distributor cap has the terminals on the top and uses a separate coil, this is typically the correct set.
What is the wire thickness?
These are high-performance 8mm leads, providing better insulation and durability than standard 7mm wires.
