Ignition Coils for Lamborghini Murcielago and Diablo 6.0 | Reid Performance

Description

If you own a Diablo 6.0 or 2002/2003 Murcielago you are probably aware of the ignition
coil
dilemma. These cars were the first Lamborghinis to use
individual ignition coils
after spark plug wires but before the use of Audi
ignition coils
. Unfortunately, the Magneti Marelli ("MM")
ignition coils
Lamborghini uses for these years are not without fault, they use small o-ring seals compressed by a metal clamp on the top of the coil, which allow water to enter the spark plug valleys which leads to corrosion of the spark plugs and
ignition coils
. The corrosion causes a weak spark, RPM hunting, engine misfire and can damage the catalytic converters. To top it off, one set of stock coil packs is a scant ,000.00 and Lamborghini only sells them in complete sets. Unlike many other parts found on the Diablo and Murcielago, the
ignition coils
are not cross-referenced with any other car.
If your Diablo 6.0 or Murcielago is doing the following, it likely needs new
ignition coils
:
Hunting RPM
Stalling while at idle
Catalytic Converter overheat light coming on
Raw fuel smell
Car not as fast as it used to be
Here's the low down on the Reid Performance (White Out)
ignition coil
:
1. 3 pin coilpack body to fit Lamborghini wiring harness;
2. Spark plug boot to match the MM coilpack height
; and
3. Upper rubber seal to properly keep water out of the spark plug valley.
The stock Magneti Marelli coilpack:
1. ,000.00 for a set of 12;
2. Allows water to leak into the spark plug valley;
3. Prone to corrosion from allowing water to leak into the spark plug valley;
4. Known to physically fall apart from corrosion;
5. Requires heavy grease to help keep moisture out of spark plug valley, which causes a mess; and
6. Not all dealers keep them on hand, which means you wait for the parts to ship from Italy.
Reid Performance vs. Magneti Marelli:
1. RP has a larger ignitor than MM;
2. RP utilizes a fitted, rigid rubber seal around the top spark plug valley and MM uses a mounting bracket to seal an o-ring inside the spark plug valley;
3. RP spark plug boot is more rigid and fits tighter than MM boot;
4. RP metal sleeve is coated to protect from corrosion, MM is not;
5. RP
ignition coil
body is exposed to prevent heat retention,
whereas MM is covered with a trim piece
;
6. Mounting: RP uses the spark plug connection (similar to later Lamborghini 4 pin coilpacks);
7.
In the pictures, the RP
ignition coils
is black and the used MM
ignition coils
are gold.
My personal Murcielago
had weak
ignition coils
; the changes were dramatic when I changed to RP ignition coils. Results may vary, but here are the results of RP ignition coils:
- Start up is constant in sound/RPM;
- Car idle is constant and no RPM hunting, even with a/c on or nose lift up;
- No low speed/low rpm hiccups;
- Power delivery is very linear, not jumpy, throughout the power band;
- The exhaust note is more clean;
- Less popping from the exhaust while engine braking and between shifts;
- Less of a fuel smell while stopped and idling;
- MPG has increased;
- The heat from the V12 and open engine bay design create a harsh environment for the ignition coils and their replacement (and spark plug) is suggested every 15,000mi/24,000km.
Pricing is for individual coil packs, a full set requires 12 coil packs.
