Starting the day with a laugh is good for the soul....Thanks bB!

 

I'm glad you find me funny. Good luck with that as long as it works for you. I've been helping people on here before you came along and will continue long after you are gone.

 

has anyone run into any problem's using the .44 gapped Iridiums? Someone suggested to me that running a bigger gap may cause hot spots and possibly burn up something....was it the cylinder? I can't remember what they said, just checking to see if that sounds familiar to anyone.

 

been running .44 for over 65,000 miles no problems

 

Yeah no problems here either. The wider gap gives a better spark for more complete combustion.
It's gotta be ok if it worked for the bB.

 

You should only be running the larger gap on the thin electrode type plugs - platium + irridum otherwise you may damage the coils on the plugs with excessive voltage which can lead to misfire and arc damage under heavy loads. Friend had a really bad running lawnmower that the lawnmower shop couldn't fix - turned out to be about an 1/8 inch gapped spark plug - thing started breaking down at idle but initially only at high rpm and when hot.

 

The switch to Denso iridium plugs at 39K has been the best indicator of a gas mileage.With the other performance add ons (ram intake and exhaust), I really didn't experience any improvement.

I had been averaging overall 30.3mpg, but with the plugs, the average over the past 4 tanks has been up to 31.7mpg.

 

How in the hell did you get this?!!!! How fast tou drive like 20MPH LOL!!!!

I use NGK V Power plugs, and get this...gapped at .029, I got 535 miles out of a tank of gas using them. I'm still running the same set of plugs and just got 485 miles out of my latest tank...in 11 days my 06.5 xb will be 2 years old with approx 45,000 miles on it, those numbers dont lie.

 

Why do people continue to spout miles per tank??? Who cares how close to empty you let it go. You are only killing your fuel pumps.
What matters is realworld MPGs over several fillups.

 

75,000 miles on the Denso's.. to repeat no mpg gain, no performance gain just durability.........

 

I have just put my second set of plugs in my car. The first set I chose the NGK V-power and I was very pleased with the way they ran. I got very good fuel economy and I drive allot so that is a big deal to me. I now work at a Toyota dealer so I was able to get a really good deal on the OE denso iridiums. I think the iridiums do help it idle much smoother and it is a little more responsive but my mpg's have deffinitely suffered. I gapped the NGK's a little wider so this weekend I am going to pull the denso's and open them up a bit and see what happens. I'll let everyone know what I come up with.

 

I'm wondering why people keep getting the Denzos instead of the NGKs.
The correct NGKs already come with the proper .044 gap.

 

so do the Densos...and I like them

 

Wasn't aware the Denzos also came with the .044 gap. Thanks for sharing Bro.

 

never install a spark plug unless you gap it yourself

 

I ran my box for 55,000 miles before I changed out the stock plugs as I saw no degradation of power or mileage. Replaced stock plugs with Autolite Irridium gapped at .044", from an Ebay dealer in Canada for $21 including shipping (dealer wanted $67 to change). The car runs just fine and still averaging 35 mpg at 75 mph with the air on. 30 miles commute each way, 5 days a week.

If you run non plated plugs and they are not all gunked up or insulators cracked, you can refile the electrodes flat and regap and reinstall, costing NOTHING.

 

For a little bit more coin you could have gotten NGKs. Not sure how Scions will work with a USDM plug.

 

they are already gapped... I just check them....

 

I guess you could check them just incase but with that cardboard tube protector thingy I doubt the gap could get altered from shipping.

 

Irridiums have really strong outer electrodes and are REALLY hard to adjust. It actually bend my gap adjusting tool trying to open up one to 0.044"
