looking to buy some plugs and wires i thinking im going with bosch iridium.but my mind is open to different brands,does anybody have input on a good brand to get or what you are running and how you like them.had good luck with bosch in other products

 

it would help to know what car and engine you have.

modern GM cars do not like Bosch plugs. our cars use a waist spark system that fires two cylinders at once. this system takes its toll on bosch plugs. the 2+ and 4+ have been tried and suffer the same effects.

I perfer AC Delco rapid fire plugs... unfortunetly they dont come in the heat range i currently need for my mods. the 3800 SC guys like the Autolite copper plugs. and also like the NGK plugs too. AC Delco acutally contracts some of their plugs out to NGK to be made. hope that helps.

 

sorry i forgot,01 monte ss 3.8


so if bosch is no good what are the good plugs for our cars?and is iridium the way to go?i plan on modding my car but i dont think it will be alot just minor stuff.(exaust,cai,etc...

 

in my opinion bosch does not belong in anything


i would go with ngk 3403 (tr55gp) platnum plugs

or you could go with ngk 7164 (tr55ix) ididium plugs

the acdelco that goes in your car is now being made by ngk, and is the 3403 plug, and its half the price to buy the ngk one

i would do ngk plugs with any form of lifetime warranty wires (i prefer standard...aka bluestreak)

 

is iridium better then platinum or the same i know iridium cost more is it because they last longer?what about denso is that a good plug for our car?sorry so many questions just trying to make a educated decision before i buy them.

 

ac delco calls plugs that are equivalent to the 3403 platnum plugs iridium,

i would run platnums in my car if your just driving normally, i've got iridiums for mine, but they're the colder plug for when i switch down to the smaller pulley

 

Are you sure you need new plugs? I replaced mine on my '01 at about '85k, and it was a waste of money. Nothing wrong with the old ones. Wires, too. Problem was the coil packs.

what about msd wires is that a good brand,i see two different kind regular or race wires.i do not race my car so are those pointless and just get regular,or are the race ones good for my car.i going to be getting the ngk's plugs

 

i personally dont think they'd do anything on our cars, they're an excellent wire, and you dont need the race wires, the regular ones are fine, but they dont come with a lifetime warranty like a lot of other brands.

 

With wires alone, dont expect any power gains from the wires alone. Even when it comes to the plugs. Switching plugs and wires alone wont either unless your cars ignition system was really worn out to begin with. It all begins with the coils.

The coil is the starting point. The high voltage it produces is what allows the sparc to arc to ground. Most systems are upwards of 12,000 volts. If you upgrade the Coil packs to a unit that puts out mayyybe 45,000 volts, you will have a better end result at the end of the plug, providing your wires and plugs can handle it. If they can you would expect a cleaner, hotter, faster spark.

As well as upgrading the packs, you will be providing an increase of positive energy. You should upgrade the source of negative energy, also known as a ground. More specifically, the engine grounds. These little buggers are usually made up of braided steel cabling. Not bad for longetivy, but high on resistance. Id reccomend using high-quality 0 or 4 guage power wire from a sub installation kit. While your at it, you may also want to upgrade all the grounds you can find.

Id also upgrade the battery terminals, and main power wires from the battery, but we'll touch on that later.

Next thing you want to replace is the wires. You will need to upgrade your wires to handle the additional voltage that they will carry, and to have lower resistance so more of the power makes it to the plug itself and not wasted as heat.

Really, when it comes to any wire, your going to want to see what the resistance per foot is, using a multimeter. Take off your existing plug wire and check it from end to end, then bring your multimeter to the parts store with you. This will give you a resistance benchmark to go from.

The width of the wire say a 6mm vs. a 8 mm plug wire is somewhat irrelevant. If you have a low resitance 5mm wire, it may produce better voltage then even a 9mm that has higher resistance.

You want the maximum voltage from the coil to reach the end of the wire. Select only the wires that have the lowest resitance per foot, as that will allowfor maximumamount of energyto hit the plug, with minimal losses as heat. From what I have found, MSD wires have no better resitance per foot as the Achellco ones. The boots are a little more solid, but overall not worth the money. At least not in my calculation. Acell wires however dd have a lower resistance but only in import applications, it will be trial and error and a few hours in a parts store maybe.

Next is plugs. Selecting a plug is up to you and your application. I wont touch on this so much, as the possibilities are endless just for N/A alone, add In supercharging and it will be a trial an error thing again.
