$849.95
Support max gains up to 180 hp and 400 lb-ft. Control key tuning features through the smartphone app. Change power levels on the fly while driving.
Fitment, device functions, installation details, and compliance notes are organized in the fields below for easier purchase verification.
$70.25
The set gives Harley owners a direct ignition-wire refresh for supported motorcycle platforms without turning the engine bay area into a universal-looking installation. The included wire ties help keep routing clean.
Confirm the motorcycle application and Delphi fuel-injection compatibility before installation. Use the supplied wire ties to route the plug wires in a factory-appearing layout.
$172.95
The ceramic boot design withstands up to 2,000 degrees F, making the set useful around headers, tight engine bays, and other high-heat areas that can damage conventional spark plug boots. The wire jacket is rated to 600 degrees F peak.
Stainless steel spark plug terminals help carry spark energy to the plugs, while the pre-made wire lengths support a cleaner fit on the intended application. Confirm boot angle, color, and terminal style before installation.

Stainless steel spark plug terminals help carry spark energy to the plugs, while the pre-made wire lengths support a cleaner fit on the intended application. Confirm boot angle, color, and terminal style before installation.
$166.95
Copper conducts electricity and dissipates heat better than platinum or iridium materials, helping reduce the chance of misfire in high-combustion-pressure applications. The gapable design allows the spark gap to be adjusted for the engine setup.
The set includes eight plugs with machine-rolled threads for precise thread engagement and torque retention. Confirm thread size, reach, resistor configuration, and heat range before installation.

$499.95
The distributor is a direct OEM replacement and is compatible with high-output CD ignition systems. Because Opti-Spark replacement is labor intensive, the upgraded construction helps support a one-time, confidence-focused repair and performance refresh.
Confirm spline-drive compatibility before installation, especially on early LT1 applications. Verify the vehicle build range and distributor drive style before ordering.
$499.95
The cap is sealed to reduce corrosion, vented to remove captured heat, and overmolded to reduce arc-over risk. A coated rotor blade and high-dielectric glass-filled cap support longer service life in a distributor location that is known for labor-intensive replacement.
Confirm that the vehicle uses the compatible Opti-Spark II distributor style before installation. Use the installation guide to verify orientation and connector details before replacing the existing distributor.
$220.95
The distributor is a direct plug-in factory replacement for supported HEI layouts, giving street vehicles a complete ignition distributor upgrade without needing to reuse old distributor electronics. Easy-access mechanical advance adjustment helps dial in timing behavior.
This version does not include an in-cap coil and is intended for the specified non-computerized applications. Confirm gear, cap, terminal, and advance requirements before installation.
$86.77
The coil is rated at a maximum 48,000 volts and is built to deliver 10-15 percent more energy than the stock coil. Brass coil wire contact helps increase secondary energy transfer.
Use this coil where the GM remote mount HEI application is confirmed. The direct bolt-in, plug-in design keeps installation focused around factory-style mounting and connectors.
$75.95
The dwell control circuit helps maintain long, consistent coil charging, while current control protects against coil overheating where that feature applies. The design helps replace weaker stock-style ignition control with a performance-focused ACCEL module.
Match this module to the specified ignition system before installation. Use the confirmed fitment data and any available installation document to verify the correct module style before installation.
$160.95
The ceramic boot design withstands up to 2,000 degrees F, making the set useful around headers, tight engine bays, and other high-heat areas that can damage conventional spark plug boots. The wire jacket is rated to 600 degrees F peak.
