Changing out spark plugs, these seem to be what they look like after 12k miles and hard driving. Seems to be just fine, but not sure if it’s more than average fouling for 12k miles only.

HI Brandon,

Okay...here is what I see. The center electrode is nice and square with no domed top. The ground electrode shows no erosion. There is no overall soot covering...however....the center electrode porcine insulator is a bit too whitish, indicating a lean mixture to a degree. A nice golden brown would be perfect....So If it were me...I would reinstall these plugs.... Why did you remove these plugs? Trying for a colder heat range?

Best,

Thank you for the insight Phil, a part of me was hoping you would reply in this thread as previously before. In your experience, they look fine after 12k miles and could use these better than the iridium motor craft if that’s what I’m understanding correctly. Since I am running lean, it doesn’t seem too harsh so no need for colder temperature? Yup I installed them to see if it would be better for the car. So far, no complaints and there was a slight sluggish feel to the car when accelerating. In addition, my car wouldn’t remote start sometimes so I thought it might help to have a better material. Sorry if I sound dumb, I’m not very mechanically knowledgeable and that’s why I’m here to learn from y’all. I had about a 50-70 hp increase from stock and I drive it stupidly hard, thought I’d give the iridium motorcraft a shot. It now has no sluggish feel when accelerating hard, but I definitely need way more miles on it before I can definitely say that. Only drove 50 miles.

Now that I am aware you have more power in the truck what tune did you get?

I have the FP tune, roush cai, borla exhaust, , mishimoto intercooler pipe kit, BOV and AFE scoop(whatever these last two actually do for the truck). Currently run a 5.5-6 second 0-60. So there’s a definite hp/torque increase. Forgot to mention, I use drive mode for first 5 minutes until cylinder temp is 195+ then I drive it on S 95% of the time pretty darn hard.

I will give credit for the fact you did get smart with most modifications and the fact you dont go into sport mode until at operating temp.

My one concern is the Blow off valve. Os it the 50/50 vent to air type? If so that might(key word) have a little to do with some stuff. When you let the air vent out you technically loose power. How so? Well the air that is recirculated does two things. 1 not hit the thottle body and bounce back at the turbocharger causing big problems, 2 keep the turbocharger spinning with a somewhat boosted air charge to reduce turbo lag. Now the second deal would be most affected by the vent to air and definitely more noticeable on a manual transmission vs automatic. Also it would cause a more rich over lean condition.

Could it still cause issues? Possibly bit since I'm not touching the truck im mot 100% on this.

Hah, I try to balance research on proper ways to treat a car/truck with the abuse I put it through. The least I can do. Maybe it will even out somewhat...

It is the vent to air type, I did notice some problems with it, some times weird chug stopping, stronger momentum with the car after letting off throttle. However, like you mentioned I did have reduced turbo lag, higher throttle response but mainly due to the two reasons you mentioned. Which, in all honesty seems like a double edged sword. My gf does not like the hiss/rigid/abrupt feeling of the BOV on so I have it off 75% of the time. I really like the increased sound of the intake and hiss of the bov, however, I am thinking about keeping it off to keep the lady happy. The truck is insanely smooth with it off, like butter, you don't even feel the gears changing as abruptly as the BOV. It's less visceral to me and less fun, but I am 95% sure that it is better for the truck and my relationship :LOL:

Mrs. Quail Guy loves to hiss at idiots on the road.....so she makes a lot of noise here in Colorado.. ;)

I don't daily drive the Ranger anymore because I needed a time out from driving her so hard. Having said that, When I was talking to her on the way into work the other day I definitely heard the Mrs catch a 3rd gear chirp coming off a light trying to get in front of someone...lol.

I thought we had an entire thread about this, and it was not recommended to run colder plugs, for a basic tune?
Ok, way off topic, but your avatar, who is the man that just schooled the great one? I gotta know.

Ok...so I had a nice chat with the folks at NGK about colder plugs for our Rangers. Here is a link to what I was pointed too.....Think I'm going to go with the Ruthenium and gap at about .026-.027
You'll notice the Ruthenium is specifically made for supercharged/turbocharged vehicles.

FYI....I did have a nice long conversation with Anthony @ Livernois yesterday about all things Ranger performance....nice dude....anyway, we did talk about plugs and he said we didn't need to run colder plugs in our tuned Rangers but it wouldn't hurt anything to go 1 step colder.

ive had those installed yesterday and I can tell the difference with the oz tune, much smoother acceleration!

Yes, I run the Ruthenium plugs. I probably have about 40K on them. They are a good plug but I would not install them unless you are running a tune in your Ranger....just my opinion.
