January 25, 2007hmmm, they must have changed it. Oh wait, that's the JET performance pack I'm thinking of. Sorry

January 25, 2007Its just like changing the plugs, you have to lift up the interior intake manifold and everything. I would do wire at the same time if you are looking into it. Recommend 8.5 wires, unless you need larger, but for most mods, intake & exhaust 8.5 are fine.
January 26, 2007Hey PT,
I'm very interested in what you're getting for mpg. I'm all about better mpg. Especially if it doesn't cost much.
Did you do plugs, wires and coil all at the same time? I'm wondering if the plugs and wires are a big part of your improvement. I changed mine over to the Cranes and NGK Iridium at around 10,000 miles and didn't see a huge diff in mpg, but it sure ran alot smoother. It was a very noticeable diff which is something I didn't expect.
Something else that may interest you would be Halo plugs. http://www.haloplugs.com/ The claims are impressive and the guarantee is even better. Money back if you're not satisfied. There's a guy on another forum that replaced 6 month old platinums in his Explorer and saw another 2 mpg. I think I'm going to try them this summer. He calims his dad helped design them.
January 26, 2007I don't remember the exact MPG figures, since I havn't driven my baby in several months due to the auto transmission, but seems like it was around 20-22; and I drive aggressively. I hope to get my blue baby back on the road in the next month, but it will be with a turbo engine and a new auto (rather have the stick, but my wife needs the auto.) The main reason for the ignition upgrades was to smooth out the idle, which it did to a degree, but the biggest overall difference was when I added the MSD DIS-2. I was already smooth at idle, but a little rough higher in the RPMs. The MSD box really helped there. It makes strong multiple sparks through 20 degrees of either cam or crank to make sure as much of the A/F mixture is ignited and burnt. I suppose that my milage would have gone up, but it's too much fun to stick my foot in the gas pedal. If you are after milage, then you will want to do the ignition stuff (the coil is optional, since the stock one seems to be fine), but I would add a free flowing air filter and muffler at a min. If you want to take it a step further, check out the hot rod guys. Anything they do that doesn't add fuel will help since it is aimed at improving combustion effeciency. I.E. lighter pistons/rods, ported bowls in the head but not the runners, AFC tuned a little lean, and a higher compression piston can help if you tune the computer right. These are just a few hotrod tricks that increase effiency (more HP by burning the existing fuel better) and don't normally require any more fuel. The exception is the hi comp pistons. Depending on the combination of mods and the total compression, you may have to add more fuel to keep from buring a hole in the piston. PS Don't buy the fuel saving magnets or the Intake Air Temp (IAT) sensor mods. Also, the benefits of a TB spacer are arguable. This is especially true with the long runners on our intake manifold. But you can do what you want, and I encourage you to search these forums and to post to others as well. Even though Bob Stocktum is a power guy, I'll be he knows a thing or two about MPG.
January 27, 2007Didn't realize this was a revived post. Sorry about that. I won't be tearing the engine apart and spending tons of money on that. I already modded the intake. Maybe I'll do exhaust come summer. I'll look into the MSD deal. depends on cost. I also plan on trying the Halo plugs. The car only has 30k on it so there is a lot of life left in it and my wife loves it. (It's really her car) I plan on getting a '97 or '98 Lincoln MKIII in the near future for me. Then the mod bug will hit me on that. At least they get 20-26 from the factory with 290 HP. Plus every bell and whistle available back then.
In July I had to replace the tranny and ever since then my mpg went way down. So next month I'm going to put in Amsoil and see waht that does for me. I was up to 23-28 mpg prior to the tranny. Now I'm getting about 20 no matter what the driving conditions are. (And I don't have my foot in it. I have to factor in the winter gas, but even so, it shouldn't effect it that much.
Thanks for the info though.
