(I wrote this a while ago, but it never showed up, so if it is floating around out there, sorry.) I put Magnecor wires in with Bosch plugs. It's not as if I am driving a hot rod now, but the difference is noticable. The RPMs seem to come up right on demand, and smoother. I usually take off from a stop by steping the RPMs up to 2k, then letting the truck accelerate through the gears at that setting (just like flying). When I do this now, it definately gets to 35 or 45 mph faster than it did before. The first few times out I had to remind myself to let the car infront of me move before I step on it like I used to do - my timing is all off. Anyway, there is one "problem" I have noticed that the RPMs are bouncing around when in idle, and I can "feel" the engine running through the steering wheel now, not like before. It isn't dramatic, but it is noticable. Is my distrubutor timing off now? Need lubrication? What? http://landrover.mrbaileyshistory.net | ||

I've got the same experience. Bosch +4's with Magnecor's, but the rough idle was present before the plug/wire change (it had Bosch Platinum's before). Very likely could be injectors worn or dirty. I'm guessing you've got a '94 or '95 Disco (or a RRC), so mileage is at least near 100K or more? That's my guess as it is not an obvious miss, nor do the RPMs seek around (it is just kinda lumpy...right?). | ||

i know how good the "expensive plugs" are in some vehicles but all I can say is disco's like the shit plugs. mine ran kinda bumpy on the NGK's now the autolites have it purring. I would say buy the cheapies and change them more often thom | ||

Not to kijack, but somebody was claiming great success with an expensive NGK plug (like $11-$12 a plug)...was that you Thom? I certainly don't have the misses others have reported with the +4's, but I'd be willing to throw in a set of cheapies (copper Bosch supers, anyone?) and give it a shot. BTW, the platinum equivalent almost always is a little hotter plug than the non-platinum plug spec'd for the vehicle... | ||

Jason- That wasn't Muskyman- I use the Bosch Super's myself (and replace often since they're cheap) and have had good luck with them. I find that changing often gives me a good feeling twice! 1. I have a chance to "read" my plugs so I feel I know what's going on with my engine. 2. NEW plugs in engine! | ||

nope that wasent me I learned my lesson with "special" plugs long ago I once paid $10 a piece for these  I ran them in a Turbo car running 22lbs of boost ...dumb idea...but I was young and stupid  | ||

I am running the Bosch Platinum singles - or whatever they are called - $1.99 ea. So they were not exactly expensive. I certainly would describe my RPM's as "bumpy" not like there is anything really wrong, but it ain't as smooth as it should be. Speaking of looking at the plugs when the came out. Mine were old - over a year!!! But they looked normal, just a little more white than they should have been. But I attribute that to the age. Except for on #7, that one was dark, almost greasy looking, and it actually smelled like gas. Is this a one time thing because I started the engine cold, moved the car 10 feet and then shut down to do the change? Or a possible problem? As far as the RPM's are concerned, I am going to do a timing check next, along with a lube on the rotar. We'll see what happens after that. If that does not fix it, I will let these plugs run till summer, then change them out for something else. http://landrover.mrbaileyshistory.net | ||

Hmmmm.... My bet is the dizzy is fine, but it doesn't hurt to check. From what you describe on the number 7 plug, either you have a bad injector that is dumping fuel...or that plug is fouled pretty bad and not igniting the fuel at low RPMs (further causing it to appear wet and greasy). | ||

Thanks Jason, that's just what I figured. So I am going to try some injector cleaner in the Chevron gas next time, then check it again after it has been driven at normal temps, and then cooled down. | ||

I paid $1.94 for two Autolites at Wal-Mart for my truck. I can replace them quite often at that price and they seem to run just as well as the stock plugs. I'm certain that my rough idle is old injectors. I just don't think the fuel mileage will improve enough to justify replacing them yet. PEace, Paul | ||

Paul, Is your LR a V-twin, inline twin, or boxer twin ??? Sorry, I couldn't resist | ||

Ya, your rough idle might be coming from the fact that you are using 2 plugs on a V8 - that might, just might cause some bumpiness in your idle! HA! | ||

I put new plugs in a month ago, don't recall what they were but they were about two doolers each. I installed my Magnacore wires (Thanks Nathan!) last night. Wow, what a freaking difference. The acceleration is so much faster and stronger. Not only that, people at work today noticed a difference. "Did you get a hair cut?", "Is that a new shirt?" "Did you get a promotion Brendan". Little did they know I just installed the new wires. I will just keep that a secret.... B.K. | ||

So what you all seem to be saying is that I, too, should have magnecore wires if I want to succeed in life. Ok. I'll order them tomorrow. Seriously, though, aren't all plug wires basically the same? What makes magnecores so good? I am ordering them tomorrow, though...That was no joke. Just wondering why these and not "Accel" or something like that. | ||

No, they are not all the same. In fact, there can be a very significant difference in them. There are other good manufacturers of plug wires including Moroso (my personal favorite) Accel, Taylor, and others. All the good wires are made to very high standards, introduce very little resistance to electrical flow, and have excellent insulation. When you get your Magnecors, hook them up to an ohmmeter and check the resistance versus one currently on your truck. Then compare the insulation and construction. Considering they cost LESS than the stock wires, you'd have to be nutty not to use them. -P | ||

Ya, you will see the difference as soon as you get them. And like I said, even though my truck isn't idleing as smoothly for some reason, the driving improvement is definately there. |
