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.

Get rid of that ugly OEM dipstick and replace it with this clean Lokar piece. It's the best dipstick you can buy for your 97 and up LS1.
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.
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.
