Product Details

The Airtex 5D1078 is an OE-replacement distributor cap engineered and tested to meet or exceed original equipment specifications in form, fit, and function. Designed as a direct-fit replacement for GM-based ignition systems, this cap restores reliable spark distribution and helps eliminate misfires caused by a worn or cracked distributor cap.

Key Features:

  • OE-grade dielectric polymer housing — High dielectric-strength engineering polymer construction prevents voltage breakdown and arcing for long service life
  • Solid aluminum terminals — Ensure superior electrical conductivity between the coil and spark plug wires
  • Durable carbon brush — Resists wear to extend the operational life of the cap
  • Anti-arc barrier — Reduces the risk of secondary voltage arcs that can cause engine misfires
  • Keyed locator design — Easy-to-read locator keys ensure proper installation orientation
  • Includes mounting clamps — Hardware included for a complete, straightforward installation

I was very pleased with my transaction with Autoplicity. My order was shipped the next day and received the following day. The pricing was also the best I could find. I would definitely buy from them again and recommend them to others.

Shipment was quicker than I thought and the product was just as described. It was cheaper than else where. Thank you Autoplicity
