Just got analysis paralysis searching here on plugs. Just really looking to see what you are running and what you think. I have the Bosch Plat +4 plugs in there now, and they have around 30K on them. Those are 30K miles filled with cleaning stuff out, etc, and I want to throw some new ones in there.
Choices:
Bosch Iridium: $4.99 after rebate (I think I run those in my S4)
Autolite Platinum: $2.99
NGK Platinum: $2.99
Bosch Platinum Plus: $1.99 after rebate

Any opinions? Only thing I don't want to roll with are the copper ones. For the few bucks I would save overall I think the platinum is the lowest level I would go with (and I think those were OEM, right?).

 

Bosch 1.99

What kind of engine temps are you running now?

 

NGK Iridium,,,

nuff said

 

Same temps, no change. I'm tired of chasing it. She always ran fine, and it just seems that everything I do just leads to other stuff. She never overheated on me once, I don't lose coolant and everything I have done has really been preventive I suppose. I just now need to find that vacuum leak (or whatever it is) and be done with it.

 

Any reason for NGK over Bosch?

 

in my opinion and in my 15+ years of experience of tinkering with cars, motorcycles etc. NGK make the best spark plugs in the industry. NGK iridiums can be found in every vehicle i own.

my ducati runs a pair of race iridiums, the same the superbike teams ran. $40 a piece. that is how much i love the products NGK produce.

luckily the plugs for our rovers are more like $7 a piece

 

Just to throw out another option to confuse you: I replaced the (probably) OEM champions at 85k miles, with Denso iridiums, and now am at 110k miles with STI 7mm wires (on it when I bought it) and have had no problems whatsoever.

 

Yeah I agree the whole plug thing is a massive headache......................

I bought sti wires last week that are still sitting in the garage I am on the fence about plugs, I want ones that run good don't have to be hi performance the truck would hurt itself trying to get out of its own way. Just good clean reliable and solid.

 

I know what you mean about confusing..... I've seen lots of folks recommending the Platinum +4's on here, so that's what I picked up today... Hoping this and my new Magnacore 8mm's solve my misfire issue that cropped up on my new beach cruiser.

 

+1 to sloppyjoes response. You will obviously get various opinions. Based on my experience NGK's are the way to go. I run them in everything I own because they have never let me down. I cannot say the same for Bosch products.
