i would think the wirng is diff for the v-afc. since the car its going in has vtec

 

anyone know why one would choose a hotter plug?
im talkin about running stock plugs to begin with, not already using some cold ones then switching.

 

What Does It All Mean?

Hot plugs? Cold Plugs? What does it all mean? Definition: The heat range of a spark plug is its ability to dissipate heat from the combustion chamber to the cylinder head. The heat range, or dissipation capability, of a spark plug depends primarily on the length of the insulator nose. The heat from the combustion is transferred from the insulator nose through the center electrode to the plug housing, and from there it goes to the cylinder head.

Hot Plug
A "hot plug" has a long insulator nose which exposes more surface area to the combustion gases. This keeps the plug temperature higher overall which is ideal for stop-start city driving conditions.

Cold Plug
A "cold plug" has a shorter insulator nose, which minimizes the amount of surface area exposed to the combustion gases. Cold plugs are typically used in racing conditions because of its ability to transfer heat out of the cylinder chamber quickly. Most turbo, supercharged and nitrous oxide applications use this type of plug because of the tremendous heat they generate. A colder plug can also minimize the risk of pre-ignition and detonation, however if the plug is to cold there is risk of fouling during extended periods of idling and low-speed operation.

Heat Dissipation
Heat Dissipation in a spark plug. Of the 100% heat generated from the combustion, 20% is absorbed by fresh air from the intake of the following stroke. 58% of the heat is absorbed by the walls of the cylinder head which hold the spark plug in place. Twenty percent is absorbed by the insulator and side walls of the plug, the remaining 2% being absorbed by the spark plug wires.

 

In identical spark plugs, the differences from one heat range to the next is the ability to remove approximately 70°C to 100°C from the combustion chamber. A projected style spark plug firing temperature is increased by 10°C to 20°C.

 

all these tech ppl seem to say NGK, bosch, PLATIMNUm plugs are the best.
and to stay away from splitfire due to poor building material.
i did some reading

 

Yea, Your Deffinatly Going To Need 2 Big Ass Bottles After All, Didnt You Car Top Out At 140mph This Morning? h4h4h4h4h4

 

i doubt he was goin 140 in a ls.
mine wouldnt make it past 125, it was bone stock though.

 

you could run a 45 safely stock with some plugwires and plugs (make sure you ignition system is up to par, ex. cap,rotor,coil ect.) to run a 55 safely ALL YOU NEED is a ignition system and copper ngks.
i suggest jacobs by far has some of the best products a little pricey though. i don't suggest ANY NITROUS SYSTEM, and if you are spraying use a fukin IGNITON SYSTEM. (also don't use a dry system, zex sylinoids freeze up alot you should of got nx wet/dry system or something of that nature)

I Was Just Making A Joke From That Fucking Gay Ass Movie

 

im a moron, i re-read ur post. i get it now, a tad late though
