Product Details

The Moroso Ultra 40 Custom Fit Wire Set delivers professional-grade ignition performance with advanced materials and construction designed for high-performance applications. This wire set features a sophisticated multi-layer design that combines superior electrical conductivity with exceptional heat and EMI resistance.

Key Features:

  • Locking stainless steel terminals provide secure, corrosion-resistant connections that won't pull loose
  • High-temperature silicone boots protect terminals in extreme heat environments
  • Fold-over crimping ensures positive terminal contact and prevents separation
  • Silicone jacket offers outstanding heat resistance and durability
  • Nickel copper alloy conductor provides excellent electrical conductivity with low resistance
  • Ferrite impregnated core suppresses electromagnetic interference (EMI) and radio frequency interference (RFI)
  • Kevlar center core adds strength and prevents wire stretching during installation
  • Conductive polymer coating eliminates voltage leakage and reduces spark scatter

Designed as a custom-fit solution, this wire set allows you to cut and assemble wires to exact lengths for your specific application, ensuring clean routing and professional appearance. The Ultra 40 construction provides approximately 40-50 ohms per foot of resistance for effective spark energy delivery while maintaining proper EMI suppression.

Great communication and fast shipping using FedEx Home. My packages can even be delivered on Saturday. Great prices on hard to find parts. I would definitely buy from again. Thanks

I just received my Knn filter. Shipment was on time. The box look beat up and deformed with a lot of tapes but the filter seems to be in good condition.

I wanted to pay with PayPal and it was blocked! Not a nice move!

BEST PRICE AVAILABLE! QUICK SHIPPING.

Great Prices! and Great Customer Service thanks again!

Fantastic company! Great selection for every vehicle and fast shipping! I will definitely shop here again.

Fast ship, great price. I will purchase merchandise from them again.

Excellent service. I called in Monday for a hard to find item which I had ordered from several other online shops who despite saying were In Stock online were not actually in stock at all and the orders were canceled after waiting a week to find out. They had the item in stock as listed on their website and shipped the next day. The price was the cheapest of anyone who actually had the item in stock by a substantial amount.

Best price anywhere for a brand name item. Fast inexpensive shipping!

i was advised by all internet sources, and the manufacturer that the part i needed was out-of-stock and discontinued, when i used google shopping, autoplicity not only had the part but they were the most reasonably priced! my order was delivered to my door in 3 days. color me a satisfied customer, and yes i will used autoplicity again, soon!
