ok im gona be doing a much need over hual on my new bronco. im think on goning with some Performance cap and rotor wires and plugs

msd coil

msd cap

bosch plugs
Bosch 4511 - Spark Plug | O'Reilly Auto Parts
an msd wires

now hers my question if i bought these parts would i feel it wile driveing i have been told if i went and installed these part it will hurt my mpgs cause of odb1 wont know how to deal with the new parts

 

obd1 will deal with them just not like an obd2 system the obd1 will increase fuel to keep up with a hotter spark in the accel plugs and the wires and cap will just make it hotter

 

OBD1 or OBD2 are diagnostic features, and I doubt they will notice hotter spark.

About the only way you will feel a significant difference with these new ignition parts is if there was something wrong with your old ignition parts that prevented them from properly igniting the air/fuel in your engine. Since most cars run around with spark plugs in varying states of wear, changing to new plugs will probably give you the most detectable benefits. You may notice faster starting, and maybe a slight increase in mileage. Similarly, if your old spark plug wires are worn out to where they're short circuiting, new wires will make a huge improvement. This will result in smoother running as well.

The other condition where the advantage of a hotter spark is realized if you significantly increase the compression pressure of your cylinder, such as with a cam change, or adding forced induction.

 

The MSD has the same usable output voltage as the stock one it just has a higher peak voltage which can only be seen at 15.9 volts so don't fall for marketing. The cap and rotor well you will nothing out of them over stock. The bosch plugs are NOT a highly regarded plug either way to many quality control issues and the resistance of the electrode is all over the place (search for bosch plugs and see the issues people have with them) . The wires are good quality but not worth the price I would much rather get a nice set of premium silicone wires from autozone.

 

thx what about e3 dimod fire plugs are they good for a 351 i herd that the 5.8 is picky when it comes to plugs

 

Agreed!

Honestly, there isn't any gains by running a platinum plug or other high dollar plugs. My motor combo in my sig is far from stock and I run nothing more than an NGK copper plug.

 

i used the same coil and cap for my truck (302) but i used accel wires and plugs. i noticed the difference just a small bit and a mileage increase. then shortly later my module went out so not sure if that had anything to do with it. but after those upgrades along with a intake, exhaust, elec fan and underdrive pulley i had 20 city mpg and a noticeable power difference

 

Platinum tip plugs will last longer than standard tips. They're good for where you want to extend the change interval, like where they're very hard to get to. I would only use Autolite or Motorcraft brands, as others seem to have variable quality. I tried Bosch platinum plugs a long time ago, and the engine idle was just not smooth with them. When I switched back to the (new) standard Motorcraft copper plugs specified for my engine, it ran much better.

As someone said, don't be fooled by slick advertisements that are designed to take your money and give you no added benefits in return.

 

a platinum will last longer therefore at a standard change interval will still be in good shape while a copper plug will be failing or will have failed before the change
if you get any msd product it is a peak voltage thing which can do some but nothing noticable on a stock setup
also the msd wires have a very low resistance which will last much longer the spark will travel as it should and arc as it should
any directional plug (not symetrical on 4 sides) can benifit in milage gains by pointing the open area (where the flame would go unimpeded out of) towards the valves
bosch suck like ngk in their own relm they are good (put an ngk in an import and watch it run like a raped ape but put it in a mopar you could do much better
also delcos are gm only they suck in anything else especially 5sfe yota motors
pick matching parts with matching oe suppliers

 

Racers used to index their spark plugs by marking the position of the electrode on the porcelain insulator and seeing where it ends up when tightened down. Then they shim the plug shoulder to aim the open part of the tip to where they think it will least block the flow. But they were done on highly tuned engines and the benefits were pretty minimal. Plus, it's hard to shim plugs in most Ford engines, with the tapered shoulders.

 

Something like a Bosch +4 will last longer, but they're as much as 4 times the cost of a Motorcraft, NGK or Autolite plug. I don't mind doing regularly scheduled tune-ups because I look at other things while I'm under the hood, so a standard plug would be fine for me. Others have different opinions.

 

its all personal preference
i run msd,cap, rotor, 8.8 wires, e-coil an bosch plat+4's on both my 460's
the air horns are gone, throttle spacer an K&N, 180* t-stats an hypertec chips
i love my setups

 

The MSD Super Conductor wires are the best you can get. They will last longer than any others and provide the lowest resistance. In my opinion the e-3 plugs are a lot of hype. The spark is only going to follow the path of least resistance. It is not going to jump to all three electrodes at once. As stated before, if you do have a noticeable change, it is due to previously worn out parts. Individual results may vary.

 

I did this tune up yesterday and my old bone (95 F250-351) is thanking me. I did the http://www.oreillyauto.com/site/c/de...3435&ppt=C0334 PLugs and accel wires -=NO=- shops had the MSD wires in stock... pissed me off to have a nice cap with the wire locks and not use them but W/E. I dont think one is better then the other in this department anyways. Anyone know of a HEI guy that didnt use the other boots ? Id buy them off them 4-Sure ...

 

i had the same problem with my msd wires, so i built both sets myself
when i start stripping the 351, everything the 460s have will go on the 351, plus a mass air swap. Thats gonna be fun, i suk at electrical
