I am impressed by the Hyundai. Though I am not a luxury car owner, nor am I interested in getting one, the guys in my office that drive $50k luxury cars were flatly impressed. I guess we'll wait and see how durable their 4.6L engine is, but that is an impressive engine. It obviously is making much more power and torque than the ford 4.6 and from what I read it is comparable to the upcoming 5.0L as well. For Hyundai's first V-8 it certainly deserves applause.

I haven't heard of a V-8 Eco-Boost any reason why not? The 6.2L does in just the F-250 and bigger trucks why is that?

It is my understanding that the new spark plugs have taller threads, and so they engage more of the 6 existing threads cut into the aluminum heads. The old plugs that came out of my truck didn't look that bad frankly. One other note, I have also heard that the longer you wait to remove the plugs, the more likely they will take the threads of the heads with them when they come out. By the way when mine were done I also had to have a coil replaced, (complete shutdown of cylinder # 4) this is what actually brought me in to the dealer. '99 SuperCab Lariat

Well I had the spark plugs replaced after confirming they were using the "g" plug. I also had a bad coil which was why the engine had started vibrating oddly, I also had them change the fuel filter. Bill came to $611, I have to change the plugs on my car soon also, luckily I can do these myself.

I am taking my '99 F-150 4X4 Lariat in to the dealer to have the spark plugs & wires replaced now that i am 7k shy of 100,000 miles. I recall in these forums there was a note about a replacement plug that has taller threads to help prevent the plugs from going through the hood, does anyone know what that part number is? I asked my dealer about the existence of a replacement plug with taller threads and they had never heard of it. If someone knows of the plug I am thinking of, I'd appreciate the information. I am thinking the part number was the same as the original but has 'g' vs an 'n' or something like that.
