Q & A

What's in the Box

Do you own a vehicle with an LS based engine, but love the looks of a big–block Chevy? These coil covers from Holley are equally at home on a 2010 Camaro or a LS swap muscle car, truck or any ride needing to cover the factory LS coils. They're ready to paint so use your imagination! The covers are easily installed by using basic hand tools. Just replace a few coil bracket mount bolts with the included ball studs and snap the covers in place.

  • Cover those unsightly coil packs on your GM LS engine
  • Ultra lightweight glass-filled nylon composite construction
  • Paint to match your color scheme
  • Trim to fit your application
  • OEM-style snap-on mounting
  • Oil fill adaptor and cap included
  • Fits LS2, LS3 & LS7 engines as well as other LS family engines using LS3 style coils & valve covers

Note: Coil cover may require minor trimming on typical hot rod or swap application. Use on OE applications may require more extensive trimming to clear factory componentry (A/C box, brake booster, front drive accessories etc.).

MSD 32813 8.5mm LS1 Black Spark Plug Wires Set
SKU-54732813
                        

The MSD 8.5mm Super Conductor Wire is "the" performance wire. Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference! In a single 12 inch length of Super Conductor Wire there is only 40 - 50 ohms of resistance! That is the lowest resistance of any helically wound wire.

To accomplish this, MSD uses a copper alloy conductor due to it's great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference (EMI) "choke". This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears. The MSD 8.5mm Super Conductor Plug Wire is available in Universal Kits.

Chevy LS1/LS6 Finned Valve Covers, Plain
SKU-5721012
                        

If you are running a '97-Up LS1 style engine in your classic street rod, these valve covers are for you. These finned covers have a cast-in breather/PCV hole in each cover. They only use the 2 end bolts for mounting (stock uses four) for a cleaner look. The sand cast aluminum construction provides stiffness so four bolts are not needed to apply pressure evenly to the gasket. Comes with gaskets and hardware.

  • Strong sand-cast aluminum construction
  • Thick side walls and gasket flanges that will not bend when bolts are tightened
  • Cast-in internal baffles
  • Clears Jesel roller rockers
  • Mounting hardware included

Note: There are no provisions for the original coil packs. Use our relocation harness to move coil packs to the fenders or firewall.
