Description of ACDelco 9628B Professional Spark Plug

Wire conductor, wire length, and diameter help provide maximum spark delivery and protection. Spark plug distributor boot shape and materials provide proper fit, installation, and water-tight seal. Terminal design improves spark plug retention and assists installation with excellent corrosion resistance. Insulator employs high dielectric materials. Coil retainer prevents fretting and micro-arcing.

Best buy for 4.9L Cadillac Deville

These cables are the best buy for your 4.9 Cadillac engine. They offer more power and performance than standard cables.

Cons
  • weak
