The distributor cap & rotor are just two pieces of this type of ignition system which is typically driven by the engine’s camshaft. The distributor is the device that delivers the ignition spark to the spark plugs at a precise time, and spark timing is critical. Any wear or component out of place in this type of system will result in failure. Within the distributor and mounted to it are many individual pieces which allow the distributor and system to be maintained and repaired to keep it in top working order.

Product Features:

• All products are constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
• Cap terminal conductor wires formed with precision guided machines to ensure precise final location in the final housing assembly.
• Terminal inserts manufactured to precise tolerances to ensure a guaranteed electrical connection between the cap conductor wires and spark plug wire terminals.
• Distributor rotor blade coated with RFI coating to prevent electrical magnetic interference with the vehicles electrical system.
• Distributor and rotor housings manufactured using the latest plastic technologies to guarantee di-electric strength and long life cycle.

The Premium DiamondFire Automotive Spark Plug is engineered to deliver peak performance and efficiency for your vehicle. Featuring E3’s patented Diamond Fire edge-to-edge ground electrode, it ensures a faster, more complete burn for smoother acceleration and idle. The innovative “diamond-shaped” side wire electrode enhances combustion by quickly igniting the air/fuel mixture, resulting in a larger and faster flame kernel. This translates to improved power output by up to 6% on average and significant fuel savings, while also reducing engine carbon deposits for a cleaner burn. Constructed with durable nickel for both the center and ground electrode tips, this spark plug is built to last. Its gasket seat type ensures a secure fit, and the pre-gapped design eliminates the need for adjustments, making installation hassle-free. Upgrade to this advanced spark plug for enhanced engine performance, better fuel efficiency, and a cleaner, more reliable ride.

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 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.
