Anybody change their spark plugs to something better then stock?? how about wires (i.e, nology)

or would this be a pointless upgrade??

 

You won't notice any performance increase with plugs and being NA. And no wires on these motors - they use coil packs above the plugs.

 

wasnt really looking for "performance gains" maybe a better idle or fuel efficiency...

so basically, save my money? lol

 

Many of us switched to NGK Iridium spark plugs once past 50k miles
They are better and work stronger than the OE ngk regular plugs
Do a Seafoam treatment before swap out

 

look in car talk, that there is a spark plug that gives out a million watts or something outrageous like that for better combustion of fuel .

 

Indeed- and realize our cars work on a very specific hi output voltage - thats why no 4 electrode bosch plugs!
Stick with NGK Iridiums- known to work good in our TLs

 

First off...copper is better conductor when compared to iridium and platinum alloys. Don't argue...you are wrong.

B...The core of the plus is still copper with just the tips being alloys of platinum or iridium. They add in longevity of the plug...NOTHING more.

III...Iridium, is extremely hard and brittle material and extremely rare as well. The melting point is 4,466 degrees F. and it is considered the densest of the stable elements. Iridium is used solely as an alloying material for platinum. Platinum alloys contains a small amount of iridium which is much harder than pure platinum.

4...Split fire - Platinum 4 - EFire - U-Groove, Etc...Are all snake oil. I've dynoed many cars and these plugs do nothing that a fresh set of stock plugs can't do. Snake Oil! Look electricity flows to the path of least resistance. Period.

Five...If you are supercharged then you should consider a plug that is at the MINIMUM...one heat range colder than stock. I usually go two heat ranges colder. Ford uses 1 heat range on the 2003-2004 Mustang Cobra and 2 heat ranges colder than normal on the 1999-2003 Lightning Pick-ups (supercharged as well).

A colder plug will pull more heat from the combustion chambers and send it into the heads and cooling system. This will keep you LESS knock constrained.

IF YOU ARE NATURALLY ASPIRATED YOU DO NOT NEED TO CHANGE HEAT RANGES.

Last...It is believed that Iridium is not from Earth.

Iridium last long time- good- because I dont like changing plugs!
Not from this planet- well neither are many of us!!!
