The Sierra 18-5358 distributor cap is an injection-molded, glass-filled polyester component designed to deliver reliable ignition performance in marine engine applications. Engineered with precision manufacturing and premium materials, this high-quality cap ensures consistent spark distribution and long-lasting durability in harsh marine environments.

Key Features:

  • Injection-molded glass-filled polyester construction maintains high dielectric strength even under elevated temperatures
  • Brass inserts prevent the formation of aluminum oxide, ensuring superior electrical conductivity over time
  • High-luster finish provides corrosion resistance and professional appearance
  • Manufactured to close tolerances for perfect roundness and secure, leak-free fit
  • Direct replacement for worn or damaged original equipment distributor caps

As expected...

most competitive price i've been able to find for the ebc redstuff. with the shipping price it is still hard to argue against such prices, along with a guild letting me know these brakes will fit on my car. +1

I placed an order with autoplicity on Saturday order number 10468 I got it today and installed my new banks ram air box and it is awesome. Thanks autoplicity my box from Banks looks like it just came off the shelf even after ups delivered it.

Autoplicity had the best price anywhere! I looked everywhere for the airaid intake system and they had it in stock. Great company!

Good product at the right price. Didn't have the same vehicle fitment as the manufacturer did.

Thier site was very easy to navigate and allowed me to search for parts just for my truck. Once I found the part, I happy to see the price was very reasonable and even a little bit cheaper than other sites. I was happy to see that I could check out with my amazon account. Shipping was prompt.
