Speed Inc
HID Conversion Kit
You can't buy a system with a smaller ballast. Fully digital, draws less than 6 amps at start up and 3.4 amps at normal operating temperature. This system provides 3200-3400 Lumens at 35 watts and an amazing 5000 Lumens at 55 watts per bulb. In comparison, a typical halogen bulb produces 900-1200 lumens.

The 55W system ballasts are about 1 cm longer than the 35W ballasts. 55w kits tend to wash out some of the color of the HID bulb due to the light output( for example, a 55w 8000k will look similar in color to a 35w 6000k kit).

Complete, “plug and play” kit, with no cutting or splicing. 93-97, and 67-69 Kits include new OE style Lense housings.

Allow 2 weeks for delivery.

Holley
Coil Covers
If you’ve transplanted a GM LS V-8 engine into an early GM muscle car, you can give it the look of a classic big block with Holley’s LS Coil Covers. The covers conceal the coils on modern LS engines, transforming the appearance to look like it has a set of large big block Chevy valve covers. These coil covers are manufactured from strong, glass-filled nylon and easily install by replacing a few coil bracket mount bolts with the included hardware.

The Holley Big Block Replica LS Coil Covers PN242-1 are lightweight and can be painted to give your vintage muscle-car’s engine compartment a retro-look. But you can also use them to customize the engine on your 2010 Camaro. Either way, Holley’s coil covers can be easily trimmed to fit over aftermarket accessory drives or brackets. While these covers are designed to fit directly on GM LS3 model engines, they also fit on other LS model engines with minor trimming and include an oil fill-tube adaptor.

    Holley
    Dual Plane Mid–Rise EFI LS Intake Manifold
  • The Holley GM LS1/LS2/LS6 2x4V dual-plane was designed in the tradition of the great dual Holley 4160 induction systems that competed on drag strips, in Trans-Am and at Lemans in the 1960’s. The technology of the LS pushrod engine is now mated with the impressive multi-carb looks and performance of the muscle-car era!
  • The dual-plane equal-distribution layout produces great mid-range torque without compromising top end power. The LS engine architecture does not utilize an intake mounted water neck or distributor so it’s perfect for two Holley carburetors and this intake manifold design takes full advantage of that opportunity.
  • Carbureted and EFI versions available
  • Power band from 1500-7000 rpm
  • Appropriate for any street/performance, muscle car, or street rod enthusiast
  • Cast aluminum construction
  • Intended for use on all GM LS Gen III engines equipped with LS1/LS2 style cathedral port cylinder heads
