D.I.Y. Spark Plugs on 09 Flying Spur Speed with pics
 

Well it was time to do the plugs on my 09 Flying Spur Speed and I just couldn’t bring myself to let the dealer do it. Always enjoy working on my own cars doesn’t matter what it is. Sure glad I did cause it was really simple and fun to do.

The parts you need from the dealer are:
1. Upper plenum gasket. P/N 07C133238F
2. 2 Oetiker clamps P/N N10201801
3. 12 Sparks Plugs P/N 101905600B (Thought I could get them from an auto supplier but they are dealer only)

Here is how to if anyone else wants to try:

1. Remove the 3 plastic clip on engine covers. Front, center & rear.
2. Unscrew the 6 torx screws holding down each air box cover.
3. Remove them with filters.
4. Unbolt the 10mm bolt holding each air box in place.
5. Lift the box out a little then unplug the mass air flow sensor before removing.
6. Be sure to cover up the turbo intakes. Really don’t want anything to fall in there.
7. There is a little sensor upfront connected to a vacuum line. Be careful with this. Just pop it off the bracket. I used a panel popper.
8. Unbolt the 2 torx screws holding the fuel rail on to the manifold.
9. Unplug the sensors at the front of the intake manifold, then throttle body sensors, then breather lines to the sides of the manifold.
10. Disconnect the intake hoses to throttle bodies.
11. Now to the rear, remove the Oetiker clamps & pull the hoses off as well the little vacuum lines beside them.
12. Disconnect the vent line on the passenger side by throttle body.
13. Unbolt the 8 torx screws holding the manifold in place and lift it off.
14. The coils come out rather easily. Once again used the panel popper to get out.

After pulling the coils and before removing the spark plugs I vacuumed the area. Could see small pieces of sand and debris around the valve cover. Don’t want that falling into the engine. Because it was my 1st time doing this I did 1 plug at a time on the drivers side. For the passenger side I pulled out all the coils and did all the plugs at once. Put the coils back in the same spot they came out and add a little Vaseline around the boot so they slip into place easier. Dealer said not to gap the plugs just put them in as is. Once done reverse the steps to put back together using the new gasket and clamps.

Little tips:
1. Clean the intake manifold and upper plenum with some Acetone or Brake Cleaner to take off the oil. Gives the gasket a good seal.
2. Tighten up the all the bolts for each side of the upper manifold before install since you got access to the bottom bolts.
3. When reinstalling & before you bolt down the manifold plug the throttle body & front sensors back in.
4. The Sensor plugs are a little tight. Used a flat head screwdriver to push the end out so they open up & come off.

Hope this helps anyone that’s into doing there own maintenance!!!

Wow! Thanks for posting!

Great post John. Very informative.

Thanks!! Gotta do this soon...

That seems amazingly simple to do - though I would never attempt it. You seem to have a lot of experience with engines, and that would be important to note with these expensive machines.

Since this is the same engine as the GT, I was told that spark plug changes for us were hideously complex and expensive. So I'm very surprised, and maybe relieved.

How long did it take you all up?

I don't even change the plugs on my Harley. There are only two of them and they are in plain sight.hilarious

I know I could but just don't want to. Lazy to the max.;)

I do have quite a bit of experience working on engines & really enjoy doing it. Never worked at a shop or ever took any schooling for it, just learned as I went along. A lot of knowledge came from working on my Grand National years ago. Had that motor out a few times.

Took me just over 2 hours to do. Wasn't rushing, few pics, few beers....... I bet I could do in 45min now. That's how fast the Bentley tech said it takes him. Hahahaha.

What year was your grand national? 87? Love those things. Seen a restored one the other day.

Thx John V for taking the time to inform.

Spent countless hours on it!!!

Nice write up. How many miles are on those plugs?

It just hit 66,000 kms. Pretty sure they are the original plugs.

Simply amazing!!:cool: Do you still have her in your stable?
