F4 Champion Coil Replacement - Plug/play

SOLVED: Plug/play Champion coil replacement

Background:
When MV F4s began using individual stick-style coils, they came from the factory with Champion brand stick coils. Then, after a time, F4s began to be fitted with Beru stick coils, with a different style connector. I have a 2005 750S Brutale with Champion coils. Recently my #4 coil died and I had trouble sourcing a replacement. A common solution on this forum is to change the connector on the loom and fit a Beru coil. I wanted a solution that retained the original connector, and also felt the Beru coils are too expensive, usually priced well over 100 euro (a piece) or more. My solution below is less than half that price and no extra cost to change connectors.

Solution:
Following a lead from a posting on this forum (a member said he used a Fiat Punto coil), I ordered a Valeo Pencil Coil #245117. This type of automotive coil is fairly common and made by other companies, not just Valeo. The one I found was approximately 40 euro.

Fitment:
The Valeo coil's electrical connector is a direct fit to the MV wiring loom connecor. However, two simple modifications must be made to the new coil. (1) The rubber boot and spring on the Valeo coil is too long. Take your dead Champion's boot and spring and swap those onto the new coil. The Champion's rubber boot and spring fit the new coil without modification. (2) the fixed mounting eyelet on the Valeo coil needs to be ovaled-out slightly with a hand drill and a longer bolt needs to be used to mount it to the top of the engine. The half-moon MV hold-down bracket is no longer used.

Although my description above may seem complicated, once you have the new coil in hand you will see this swap takes minutes and is a clean and easy fit.

Source:

There are dozens of Ebay sellers in Europe selling the Valeo Pencil Coil #245117. Valeo isn't the only company that makes such a coil, cross reference for other makers.

Excellent work and thanks for sharing!

Just for future reference, would this work on the 2010 and forward models?

Update: After 3,000 miles the Valeo replacement coil is continuing to work well in cylinder #4. Then, with the vehicle mileage at 24,000, I had my second OEM Champion unit fail on cylinder #2. I have replaced coil #2 using the procedure above, using a crossed-referenced NGK unit (list of cross referenced coils to follow). While I was making the swap I snapped a few photos to add to the description above.

Here are the two coils. The Champion is on top, and the "Fiat" (meaning Fiat-type) coil is below. You can see that the Fiat-style is slightly longer, the additional length as a result of the longer rubber boot.

Removing the rubber boot and spring is easy, here are the pieces side by side for comparison:

Just remove the boot and spring from the Fiat-style coil, and replace them with Champion rubber boot and spring to form a hybrid. Fits perfectly.
