Is there really that much of a difference between using factory spark plugs vs. aftermarket spark plugs?? I just want to know if I should even bother paying extra for the "other" stuff.

 

yes, there is a difference, not a huge difference, but you get what you paid for. don't cheap out on your spark plugs, without them, the whole process of an gasoline powered internal combustion engine would be a pipe dream.

factory or OEM plugs are fine, platinum and iridium are better.

 

Thanx for the info. I'll probably go with the iridium or the platinum then.

 

I have found these platinum plugs are the best value.
Buy at Rockauto.com for 2.41 each.

NGK Part # 7090 {GP-Series #BKR5EGP}

http://ngk.com/ has a great website.

I replace every 12 months. - I do approx 35,000 - 45,000 miles a yr. When I replaced my stock plugs the first time - I was suprised that the electrodes were quite worn on a couple of them. Never really seen this in any other auto applications.
These plugs have been great - and a no brainer to replace once a year fro $10 and 10 minutes in time.
Personally I don't think the iridium are worth 3x the price on our little 1.5 engine.
Hope this helps.

 

wow, 2.41 isn't bad at all. i'll probably take this route.

 

Does the ol' "butt dyno" feel like your getting more power? Or do you just feel these last longer than the stock plugs?

 

no power gains.....I run iridiums

 

Exactly right! Run the NGK Irridiums. Get the part number for the bB and not the xB. They come pregapped at .044. You will se better MPGs, smoother idle and more power. Also remember to reset youe ECU by pulling the fuse for 10 minutes after the plug install. Good luck and let us know how you like the results?

 

Here is the link to the plugs for 30 bucks shipped.

I paid a lot more than that for my Denso's

 

Running Denso Iridiums in my Supra, gotta admit it starts up in 1-2 less cranks in the extreme cold now.

 

which fuse is it?

 

Thanks for the link, just bought some. been wanting to do them for awhile. Hopefully they will help out my little idle issue i'm having.

 

Bumping, I would like to know also. Thanks....

 

It's the AM2 fuse in the engine fuse compartment.
15 Amp, fourth down from the top in the middle column of fuses. There should be a diagram on the inside of the fuse block cover with fuse labels and location.

 

Thanks man, appreciate it.

 

Much appreciated my friend!

 

Incorrect, pulling the AM2 fuse will NOT reset the ECM, it does not terminate the battery source.

The battery source is supplied through the EFI fuse, only pulling that fuse or battery dissconnect can reset the ECM.

 

My mistake, the AM2 goes through the ignition switch to turn on the ECU, but the EFI is the one providing primary battery power. It's been awhile since I had to pull the fuse.

 

I purchased a set and installed mine last week. Itook the car on a beach trip this week and ended up averaging about 35.4 mpg with aggressive driving. Probably wouldn've been a lot better if I drove conservitively.
