Moroso Ignition Wire Super Loom Kit for Small-Block Chevy — Black 7–9mm, Chrome Brackets & Multi-Hole Looms

Moroso 72174 is a complete black ignition wire super loom kit designed to organize and protect 7–9mm spark plug wires on small-block Chevy engines.

This kit supplies the mounting hardware and molded looms needed to route and separate ignition wires cleanly along valve covers and engine sides. It’s made for universal fitment but specifically matches the layout of most small-block Chevrolet valve covers, helping installers create a tidy, insulated harness that reduces chafing and simplifies service. The components are chrome-plated where exposed for a durable finished look and the black looms keep the engine bay visually neat.

How does this kit keep ignition wires organized?

The Moroso super loom kit uses a mix of multi-hole looms and separators to group and guide individual wires along fixed paths. Mounting brackets secure the looms to valve covers so the harness follows a consistent routing, preventing wires from crossing hot components or rubbing on sharp edges.

• Two 4-hole wire looms to cluster multiple wires together
• Six 2-hole looms for tighter spacing or secondary routing
• Two 4-hole and two 2-hole separators to keep bundles apart
• Two right-side and two left-side chrome-plated brackets for secure valve-cover attachment

Will the parts fit my small block Chevy or similar engines?

The kit is marketed as a universal fit and is especially well-suited to small-block Chevy valve-cover layouts because of the included left and right brackets. Measurement and visual confirmation of your valve cover spacing will ensure the best match, but the variety of loom sizes makes the kit adaptable to similar V8 configurations.

• Compatible with 7–9mm diameter wires commonly used on performance and stock engines
• Chrome-plated brackets match many valve cover bolt patterns for small-block Chevy
• Multiple loom sizes provide flexibility for different wire spacing and coil locations

What materials and finish should I expect for durability?

The mounting brackets are chrome plated to resist corrosion and present a polished engine-bay appearance, while the looms and separators are molded in black plastic that resists abrasion and heat exposure typical in engine compartments. The kit balances durability with lightweight components so it won’t add significant bulk.

• Chrome-plated brackets for corrosion resistance and visual appeal
• Molded black looms and separators for abrasion protection
• Lightweight construction that won’t interfere with existing engine clearances

How does installation work and what hardware is included?

Installation is straightforward: position the chrome brackets on the left and right valve covers, snap the chosen looms into the brackets, and route individual wires through separators as needed. No special tools are required beyond basic hand tools to fasten the brackets to valve-cover studs or bolts.

• Includes two right-side and two left-side chrome-plated brackets for mounting
• Multiple 4-hole and 2-hole looms and separators for flexible routing
• Intended for bolt-on installation using existing valve-cover fasteners or studs

Who is this for? The Moroso 72174 super loom kit is a practical choice for home mechanics, restoration shops, and performance enthusiasts fitting or tidying ignition wire runs on small-block Chevy engines and similar V8s. If you want a cleaner engine bay, simplified wire routing, and corrosion-resistant mounting hardware for 7–9mm wires, this kit provides the essential pieces to create a professional-looking, protected ignition harness.
