I have heard mixed reviews on the Bosch Platinum +2 or +4

but the Land Rover Genuine Parts plug made by Champion is called a "Double Platinum". The plugs I picked up, the Champion 7318, are the Champion OE equivelent to thier Land Rover proprietary plug and they are also call ed "Double Platinum"

Muskyman, your not being a smarty, but for clarity....

You are saying that the Bosch +2 or +4 plugs are not good in a DII

However

The LR Genuine Parts double platinum plugs made by Champion for the DII are OK and subsequently the OE Champion 7318 double platinum plugs are also OK.
Correct? - This is where I'm not sure what you are saying.

I'm also not clear on what you mean by "good old copper cores" do you have a part number?

This becomes a vague subject without the specifics. For instance just to say platinum is bad is confusing since the LR Genuine Plugs are "platinum" and are good but the Bosch +2 +4 are also "platinum" but are bad.....

Thanks
Brian

Right on.

Just out of curiosity I called Federal Mogul/Champion and they confirmed that Champion 7070 is a direct, same as, replacement for the RC11PYPB4. Unfortunately they are not widely distributed.

Thanks

Done!!

:victory::wings:
Ok, Done with the plug and wire swap.

Spark Plugs
I went with the OEM Champion plugs, these are the exact same plugs they sell at the dealership for a 2001 DII.
Plug ID # is RC11PYPB4
Champion Stock # is 7070, sold in boxes of four.
Dealership price is $19 per plug.
Most Land Rover focused online retailers have them for $12
NAPA price was $5.49 per plug and they were in stock, thanks NAPA!

Spark Plug Wires
Magnacor 8mm
Inventory # 80242
Note that the stock wires are 7mm, the extra mm gained from the 8mm wires is insulation which provides about 100 degrees of additional temperature tolerance for these wires, extending their life. These are highly recommended on all of the Land Rover forums and have proven to be a solid substitute for OEM wires.
Most online retailers have them for $100-$111, Magnacor sells direct to the public too and quoted $130 for the set before shipping.
I purchased my set from Apex Performance .com. They sell them for $85.90 and I used a 10% coupon code from a BMW forum, for a final price of $77.
This is compared to the dealership price of $45 per wire, $349 for the set of 8.

Installation took about 2.5 hours going very slowly, I wanted to be methodical and I was also just taking my time to enjoy the job. To do it again I could probably crank through it in an hour. I replaced all the plugs first and then disconnected all of the wires from the coil packs. I then found exact matches for the new wires using the old wires so I would have no issues with length. I numbered each of the new wires with a sharpie and used a diagram of the coil pack sequence to connect the new wires.
I also disconnected the battery while working on the coil packs just in case, I had no idea if I could be shocked or not so better safe. An added bonus to disconnecting the battery is that it cleared the soft codes and the SES light went out. So far I have two key sequences and about three miles with no SES light. The engine sounds great, back to normal with no sign of misfire.

Thanks again for all of the help with information.

Hate to dredge up an old thread here. As I go through the Champion Website finding compatible plugs for a 2004 DII is difficult. Will any plug rated for a DII 1999-2002 fit in an 03/04?

I'm not too sure Bill.
I would recommend calling Champion and asking them what they which plug is correct. You could also get the number off one of your existing plugs, tell them what it is and ask what the equivelent is.

Champion was great and easy to talk to when I called to verify mine.

Yes, the inexpensive Champions are fine. And go with wires from Kingsborne.com. $40ish+SH for the set, and high quality.
