I am going to change spark plugs soon and need some opinions on what type to use,
E3, bosch Platinum +4, or bosch Platinum 2.

 

To be honest - your best bet is to stick with the basic OEM style spark plugs. Too many people have had too many problems (misfires, etc.) by trying to mess with anything like the E3's or similar.

There are a few threads here and there on the forum about this.

 

X2....................just changed mine at 105,000 KM's. Hard to ignore the fact Champs lasted that long and never missed a beat.

 

Love the E3 on my second set had one misfiring after about 20,000 miles.

 

got about 120,000km on a set of bosch plat.+4,have used these plugs in may last 4 gas engines with no issues.about to replace with fresh set due to milage on these.

 

Don't bother with plus 4s. Get regular electrodes and save your money.

 

NGK iridium gets my vote

 

I am using E3's I got them for for 4$ a peace so not to bad of a price. 43000km not a single problem

I am wondering if there is a wire set for our jeeps? possibly a more powerful ingnition box?

 

This is like asking what type of oil to buy....too many options and opinions.

I can tell you this....they can be a pain to change out. Lots of guys end up with broken or stuck on wires and you have to be part contortionist to reach the passenger side rears.

 

I had a thread about this a week ago and after going ti the parts store I am thinking about a totally different plug I am going to try. It is a Pulstar dual prong iridium. I think that a hotter burning plug may help my hesitation at low rpm's. Not sure if my thinking is correct but I am hoping for a more complete burn in my combustion chamber.
