E3 – DiamondFIRE Automotive Spark Plug: More Power, Saves Gas (Part No.E3.42)

DiamondFIRE Automotive Spark Plug: More Power, Saves Gas

from

$7.49
The Spark Plugs are the product of years of fundamental research in the combustion field. The unique patented electrode configuration of these new The spark plugs increases the amount of combustion pressure created during each power stroke of an engine, which results in a marked increase in power output, fuel economy, and reduced emissions in all gasoline engines. E3.42 is a 14mm, 0.460 reach plug with a taper seat. It fits domestic applications in the 80s to early 90s, and is widely stocked in automotive retail stores. The automotive plugs have three legs securing the Diamond FIRE electrode to the shell. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. The patented Diamond FIRE side wire is proven to increase power, reduce fuel consumption and improve hydrocarbon emissions in long-term use.

Product Features:
  • E3’s Diamond Fire edge to edge ground electrode provides maximum performance with increased efficiency and a faster more complete burn.
  • Smoother Acceleration & Idle – The faster flame initiated by the The spark plug results in a more complete burn of the ingested fuel charge. More pressure is created against the piston more fuel is put to work
  • Energy – Power output improved up to 6% on average in the typical operating ranges. Results will vary.
  • Efficiency – The “diamond shaped” side wire electrode projects the combustion spark in a way that more quickly ignites the air/fuel mixture, thereby creating a significantly faster and larger flame kernel. The result is that more fuel is put to work durin
  • E3’s patented Diamond Fire Technology provides a cleaner burning combustion, which translates into fuel savings and reduced engine carbon deposits
  • The Spark Plugs are pre-gapped at the factory and cannot be adjusted.

MSD Ignition – Crank Trigger Kit; Flying Magnet; Big Block Chevy (Part No.8620)

Crank Trigger Kit; Flying Magnet; Big Block Chevy

from

$481.99
For a long time, racers have known that one of the best things to do to an engine to improve its performance is to stabilize the ignition timing. The MSD flying magnet crank trigger system does exactly that by using magnets embedded in an aluminum wheel. The MSD flying magnet crank trigger uses four magnets secured in the aluminum trigger wheel that pass by a stationary non-magnetic pick-up to trigger the ignition. This flying magnet design produces accurate trigger signals and the non-magnetic pick-up cannot be false triggered. Each flying magnet crank trigger includes a two-piece mounting bracket for the non-magnetic pick-up that in most cases will work on either the passenger side or driver’s side of the engine (the SB Chrysler and SB Ford brackets mount on only one side). The adjustable bracket provides a wide range of timing adjustment and spacers are included. These systems will trigger MSD 6, 7, 8 and 10 series ignitions and all MSD timing accessories.

Product Features:
  • Absolutely The Most Accurate Way To Trigger The Ignition
  • The non-magnetic pickup cannot be false triggered.
  • Powerful magnets are embedded in a billet aluminum trigger wheel.
  • Incl. brackets/mounting hardware to fit a variety of engines

MSD Ignition – Wire Set; Black Super Conductor; Big Block Chevy with HEI Tower Cap (Part No.35603)

Wire Set; Black Super Conductor; Big Block Chevy with HEI Tower Cap

from

$143.99
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, 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) or 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. Available in universal kits and bulk lengths.

Product Features:
  • Less than 50 ohms per foot for superior spark
  • Ferro-magnetic impregnated core creates an effective EMI choke
  • 40 ft. Of Conductor Wound Into A Single Foot Of Wire
  • For high EMI suppression
  • Conductor core features Dupont Kevlar material
  • Proprietary compound sleeves for resistance to high heat/abrasion
