2003 Chevrolet Corvette Ignition Coils and Boots

“The Holley LS coil offset bracket was designed for use on vehicles equipped with Holley LS valve covers and high-mounted driver’s side alternators. The bracket installs directly to the existing coil mounting posts and allows roughly 1″” of extra clearance. This assembly was developed for use only with Holley cast aluminum LS valve covers with coil mounting provisions (72mm bolt spacing) and 5th gen LS coil bodies. Each bracket assembly includes one LS coil offset bracket and two mounting bolts.”

GM Genuine Parts Studs are designed, engineered, and tested to rigorous standards, and are backed by General Motors. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

“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 8 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, we use 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’s 8.5mm spark plug terminals feature Dual Crimp terminals. As the name implies, the terminals feature two crimps, one for the sleeve of the wire and another separate crimp to grasp the conductor.

UNIV. LS PLUG WIRE SET FOR HOLLEY SMART, 561-113.

Mallory Pro Wires are a perfect fit for your street rod, hot rod or daily driver.

Modern vehicles may have 100 or more electrical harness connectors in every operating system of the vehicle. Terminal tension may weaken with time or corrosion may occur within the connector housing making replacement necessary. When replacing any harness-connector assembly approved wire termination methods must be followed to ensure a successful and long-term solution to the original problem is made. A failed terminal connection, terminal corrosion or damaged wire will result in an electrical system fault.

An ACDelco GM Original Equipment Ignition Coil is a GM-recommended replacement for your vehicle’s original component, and undergoes more stringent testing than aftermarket products. It increases electrical system voltage to help ignite the airfuel mixture as the starting and charging system starts the engine, maintains the battery’s charge, and provides power to the electrical accessories while the engine is running. An ACDelco GM OE Ignition Coil uses pure copper windings to improve durability and provide higher resistance to internal shorts and dielectric breakdown. Because the number and shape of the laminations determine the output characteristics of an ignition coil, ACDelco ensures that the silicone steel plates surrounding the coil correctly match the original part size and number. Since steel laminations work best when they are new, shiny, and clean, ACDelco laminations are coated to hinder corrosion and many feature molded plastic protection to help ensure that nothing is exposed. This original equipment ignition coil has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Look no further when it’s time to tune-up your LS. Bolt on legendary ignition performance with MSD’s direct replacement coils. Reliable parts from the ignition leader at a price that won’t break the bank.

MSD’s engineering team has been working diligently the past year to improve our Multiple Spark Coils for the GM LS-engine platform. The coils fit in place of the OEM coils yet are capable of delivering higher spark energy to the plugs, topped with multiple sparks at idle rpm. Increased spark energy and voltage, along with multiple spark capabilities, help improve the combustion process of the fuel mixture to create an efficient burn. This results in improved throttle response, smooth idle and quick starts, plus increased high rpm performance.

Do you have a built LS with bumped-up compression, a cam, or intake, How about Nitrous or Boost, Did you think about added spark energy to squeeze all the power out of your power adders,.

Looking to replace your worn out LS coils with a more efficient upgrade, The new MSD Blaster LS Coil line is ideal for your modern GM muscle car or truck. The coils are designed as a bolt-in replacement yet have been thoroughly tested and detailed by our experienced engineering team.
