Detailed Description

Prenco 36-8178 is an ignition coil built for specific Mercedes-Benz ignition systems where the coil body is serviced separately from the boot. This part number is used across several late-1990s and early-2000s Mercedes-Benz platforms, including SL600, CL600, S420, S500, S600, SL500, and E420 applications. If you are replacing a failing coil on a Mercedes-Benz SL600, S500, or S600, this part number helps narrow the search to the correct coil-body-only configuration.

This part cross-references Bosch 0221504001 for the same application.

What It Helps Address

• Engine misfire caused by weak or failing ignition output
• Rough idle on Mercedes-Benz V8 and V12 engines
• Hard starting related to inconsistent spark delivery
• Loss of power under load from ignition breakdown
• Check engine light conditions tied to ignition coil faults

Installation Notes

Verify the vehicle uses the coil-body-only, w/o boot configuration before ordering. Confirm the part number, connector style, and mounting location against the original coil on the vehicle. This ignition coil is listed for N/A position applications, so match it to the existing component rather than a side-specific location.

Compatible With: 1996-2002 Mercedes-Benz SL600, 1998-1999 Mercedes-Benz CL600, 1996-1999 Mercedes-Benz S420, 1996-1999 Mercedes-Benz S500, 1996-1999 Mercedes-Benz S600, 1997-1998 Mercedes-Benz SL500, and 1997 Mercedes-Benz E420.

Quality Assurance

Prenco replacement ignition components are cataloged to match specific OE-style applications and interchange references for accurate fitment selection. Use the original part number and vehicle details to confirm the correct ignition coil before installation.
