Where are they hiding the Spark Plugs on this engine?? I haven't looked since last fall but I need to stick new plugs in my D!

I used a LED flashlight looking all over the top and sides. Are they under a shrowd? I don't see any regular silicone plug wires anywhere, just regular looking wire going into some capped devices.

I must be a noob on this engine. All I have done on my own with it was put in an Airaid Intake and Throttle Body and change the oil a few times.

Hi Warren:

FF has a good link posted for you on this. I did the plugs on my o1 4.7, and they were not hard at all.

Mounted vertically under separate coils are the 8 plugs. There is a small electrical plug and one 10mm nut holding each coil in place.

The engine likes the Champion oem plug best.

They also like NGK V-powers, but those are a little harder to find.

If you are referring to a throttle body spacer, that doesn't do anything for performance on these newer engines. If you were referring to a complete throttle body, disregard these last two sentences.

 

Ya, I got an AirRaid Helical TB Spacer. Combined with the CIT I get 14mpg Local and 23mpg on the Interstate, fully loaded at 70+mph. Not bad for a 4.7 with a 4.10 Rear-end. I never did get a computer module installed to compensate and tell the engine it is running a 4.10. Was afraid to since the mileage is so good, power is too. Pulling a 28ft 6000lb camper with it. Of course I only get 9-11mpg doing that.

 

Ok, so they are using independant Coils on each plug, I think I was looking at them then. Doesn't sound too bad, wait for some warmer temps like next weekend and I'll give it a go.

Thanks for the Link!

 

No argument over the CAI, that does help our engines. Its on the wish list for my wife's Dingo.

However... I bet you that if you took off the spacer, you'd get the exact same MPGs. TB spacers were designed for throttle body injected engines or carbs, not the newer port injected vehicles like ours. They do absolutely nothing, they are a pure marketing gimmick for most newer engines.

I know the below thread is for slightly older engines (in a previous generation of vehicles), but it still applies to these engines as well. You don't even have to read the whole thing, just the first half or a little more.
