Ok guys, here i go again

I may have the wrong spark plugs.

I have read the RAVE on tuning and it keeps talking about up to 99MY and after 99MY.

Can somebody explain what this means. I have a first registered 96 P38A 4.6. What plugs should i suse,

Tha manual says Champion plugs, there are two types
RC11YCC and RC11PYB4, which plugs will suit my Rangie.

The plugs i used are Champion RC11YX, are these the wrong plugs.

I'm not familiar on the Champion plugs (which I believe are owned by Ford). However if they're making the engine run ok with no lack of power, just leave them in. Seeing you only recently bought the P38, do you know from the previous owner how long they've been in?

The average turnaround for standard plugs should be around 30,000kms.

If i were you, you'd might consider putting in a set of NGK iridium plugs. They cost around $110 on ebay. They make a noticeable difference in power & economy, well worth it I reckon. Plus they last up to 90,000kms. Check it out!

Intersting post. What are you getting l/100 on the NGKs?

I was averaging around 15 - 16 litres per 100 km(highway cycle), with the NGK I reckon it reduced by about half a litre per 100km. I'd say about a 5% reduction.

Also the exhaust wasn't as smelly, which meant it burnt more complete. Power wise, it made the engine slightly more responsive and smoother with a bit more getup.

I am averageing 12.5 per 100klm highway and what you are getting around Canberra. I just looked on RAVE and saw these plugs and put them in.

That's pretty good. I average about the same. What amazes me is that I get about 16l/100 highway when I tow the caravan - pretty good I think

Pre 99MY = GEMS; LUCAS

99MY and onwards = THOR; BOSCH

It has been established that you have a GEMS motor in your 96MY P38 so use those or equivalent

No, not the "wrong" plugs

"Stay Calm -read the chart" ;)
https://www.championsparkplugs.com/learning-center/article/227/champions-numbering-system

under "Learning Center" click on Champion's Numbering System... the chart should show immediately ... it won't link direct


In your case,
The "R" means Resistor (to stop radio interference)
C means a 14mmm thread and a 5/8" hex(spanner size) and 3/4"reach into the combustion chamber
11 is the heat range... you can use either 11 or 12 in a 4.6
Y means a standard projected core "nose"
X is a fine wire ; PBY4 is platinum multiple ground electrode, 4 is the wide gap to meet Californian emission regs; YCC means standard nose, double copper (ground and centre electrode)

BTW ...where did you get the RC11YX plugs? there's very little reference to them on the Net... there's reference to RN11YX it's just the hex spanner size 5/8" vs 13/16"

I got them on ebay from roverlords, they are a pretty good shop.
