How To: Spark Plug Change (1 GR-FE)

You mean a 3/8"? Why bigger?

 

Most of my sockets that I already own are 3/8", I had to get an adapter to use my existing sockets. This is also rated for "Motorcycles, bicycles, and small equipment", so the torque settings range is limited for heavier duty torque requirements.

 

What is the final word on the anti seize? Yay or nay?

 

I'll be changing mine out soon. If I use anti seize I'll go with the Aluminum anti seize.

 

Mayday, mayday! This may have been answered but... I just changed my plugs in my 2013 and my MPG is now ~half of normal! I'm gonna check to make sure everything is plugged in right but what could I have done wrong? No check engine light

More like a 1/3 of normal

 

Maybe the plug gap!

 

.04 on all- standby I think I called SOS too fast. It's normalizing I think. This is all with Ultragauge

 

Did you mean .040 on the Gap?

 

No. 0.040

Ah so yes to your corected

 

You should be good with the gap.

 

Went to the stealership for the leaf spring recall.

Hopped on the forum to get the part number for the plugs and cause I could remember if I changed the spark plugs since I've had the Taco.

Found this thread, amazing, and replaced them this afternoon.

I will attempt to post pictures later but at 144294 miles the original plugs were still in. I replaced them and gaped the old ones ranging from 0.07 to almost 0.08.

Thank you guys for posting and being awesome.

 

Thanks for this write up and all the helpful info on here, Just finished my plugs. Pretty easy, took about an hour and 15 minutes.

 

Nice! What gap did you go with? Thanks.

 

.042 Old ones were that and new ones were that.

 

Thanks everyone for the how-to's - did my plugs yesterday. Little over an hour to complete, thanks to the detailed writeups! Old plugs were in great shape - 42,000 km on them with a gap of .041 and clean. Denso plugs in and good for another 45,000 km's. Cheers

 

Finally got around to changing my plugs at 75k miles....and what a difference. The Denso plugs had eroded to .050, but the NGK plugs were at .060+. Trucks accelerates and runs much smoother. Took 2 hours as reported, most of that on the drivers side...

 

Denso were definitely in better shape in my truck also. Glad I replaced all of them with Denso!

 

So, today I went to all the local parts houses asking for plugs for my truck and telling them I wanted the NGK's (I am an NGK man), and all of them tell me that the OEM plug is a platinum, I didn't even bother getting into an argument with any of them, most have never been under a hood anyhow. So no one had the plugs I wanted, they had to order them, picked them up this afternoon and forgot to buy a long pair of needle nose. Wouldn't ya know, one of my boots stayed on the plug, SMH! Anyhow, I found that the P.O. Had put motorcraft platinums in it, . These things looked worn out, what do y'all think?
At least nothing was fouled or not burning, all look the same. Im shocked how white the porcelain is, usually when I see plugs that clean its after a nitrous pass at the track.

 

great write up, sub'd

 

DOse the computer need to learn your driving again beacause the new plugs? I just change mine at 95k and when first starting to drive it felt like it was gonna die till I got about a good 20 min of driving now it's fine. What do you guys think?
