Spark plugs for gen 3?

[cbrtrx]

Go to any part retailer and put in the information for a 2018/19 and the plugs listed are different than 2020.
Also the stock 2018/19 plugs from ford are discontinued

This is correct I looked this up as well. I'm not surprised they went to a cooler plug stock though.

With as much compression as they run I’m not surprised either

Damn I ordered a whipple kit from beefcake and the spark plug option was the ngk6510, pbd also was recommending those plugs for their builds. Whipple gen 5 install instructions that I saw online said :

"(Complete kits) Gap the supplied spark plugs to .028” (NGK out of box is .050”). Only use a .28” feeler gauge, any other method will lead to inconsistent results. Install the gapped NGK LTR7IX OR ITV22 spark plugs."

Just gapped mine yesterday, but I will do more research and may order colder plugs...

I’m not sure why but Ford only made this change for the 2020 model year. 18 and 19 are still the same NGK 6510

May go with ruthenium, supposed to be the most durable plug material from what ive heard and this is 1 step lower I think than the ngk6510's atleast according to brisks cross reference brand heat range chart

NGK Ruthenium LKAR8BHX what do you guys think of this?

If you want to run them for 100,000 miles then yes there good for lasting a long time. But spark plugs degrade overtime so I never let my plugs go that long so spending the extra money doesn’t make sense if your like me and change your plugs every 50,000 miles or less

changed it to what?

CYFS-12Y-T6

I run a NGK 6510 at .022 on E85, at 1000whp on my 2019.

If you speak to Whipple now they will insist on the itv24s for gen 3 boosted. Also the spark plug gap should never be opened up or closed more then .006 from its original gap to maintain proper performance, you want the ground strap to be as close to parallel as possible. Gapping a .050 plug down to .028 is a bad practice. The itv24 comes around .029 from the factory. I have a feeling most tuning shops don't even know the GT comes stock with a 7 heat range now.

Something else to mention, the ngk 6510 is a projected tip spark plug just like factory which would be much more likely to misfire but should offer better idle and low rpm driving characteristics.The denso and brisk are both non projected tip race style plugs that should withstand misfiring and greater cylinder pressure, basically designed for boosted applications. Most boost/nitrous applications will never recommend a projected tip plug like the 6510. Many times with plugs it's a compromise to what's available for the application though. I know on other platforms I've owned many times there was no actual correct plug and we had to make do and just replace them very often.

I have had no noticeable negative effect of running the stock 2018 plugs with e85, and apparently there are many ppl running the 6510's boosted with ~1k hp. What would the actual benefits be for running colder plugs? Would the ideal heat range be different when running e85?

The colder plug would dissipate heat faster and be safer when it come to preignition and misfires because it is not a projected tip plug like the 6510 is. Downside is the idle characteristics could be a little worse with a non projected tip plug.

A 7 heat range is fairly hot plug for a 12/1 compression engine and anything over 10 lbs of boost in my opinion. There must be a reason why ford switched to a 7 heat range on a stock car...

+1 on NGK 6510

Depends on what fuel you plan to use... i dont like the idea of running colder than a 7 on e85. Pump gasoline? Sure.. maybe an 8, but many of these 1000+ cars are on straight e85 all the time.. mine included. 6510s work just fine.

Anyone tried these spark plugs though ?

I am installing my ODIN SC the coming weeks and wanted to make sure if the factory spark plugs really has to go! My car has 3000 miles on the ODO?
Or I will just get the 6510's as many would recommend. ? they're not crazy expensive and replacing them every 10K - 20K won't be an issue IMO.
