How to Select Spark Plugs for Your Engine

Just like choosing a girlfriend! If she's too hot she will detonate often .she's too cold you ain't making any !

Useful info, thanks!!!

Very disturbing when the commentator's eyes are locked on to the camera.

Wow, great video.

Go watch Richard Holdener he's videos he tests a bunch of stuff on spark plugs and no power different you can check out engine masters they did a video on different plugs and same thing

I have a 2014 Town and Country Van. I changed the spark plugs and coils on my van. Engine still shakes when started. I wonder what it could be. Falty plugs and coils?

THIS IS NOTHING INFORMATION. WORD SALID BULL SH*T ..JOKE

Easy enough, use the ones recommended by the manufacturer !!

How about the recommended spark plugs that performance head manufacturer give in their instructions? Are they good recommendations or should they be scrutinized? Thanks Holley🏆💪

Heat ranges are flat out confusing when swapping over brands. Most, the lower the number, the hotter it is - except for Bosch and Accel [to pick two I know of], which adhere to the opposite. Champion? Bring a decoder ring, cause I can't explain their method - some sort of hybrid nuance happening there. Denso seems to have the most coherent scaling, but some would rather not have so many numbers to choose from and live in a 1-10 world.

Do you have a spark plug recommendation for a 13 Mustang GT NA on e85 w/full bolt ons?

great video, but im getting sea sick. HOLD THE CAMERA STILL !!

When indexing a plug how do you address the tapered plug? Getting a seal and proper index

I need to know which the spark plug is good to Mitsubishi 1988 Colt 3 cylinder, thanks

People post videos to not answer shit SMH

LOL!!! No one is using the same spark plugs for 150,000 kilometers !!!
Get real !! Most will fail between and will be replaced around 15-45,000km

dam guys really? ur trying to get 30 bucks out of us for that little tiny tub of dielectric??

??? u said iridium has a lower resistance than copper?? thats not true, copper has a lower resistance And higher conductance

Amazing video, going with ruthenium hx plugs for my boosted c7 , one step colder

can i use platinum or iridium plugs on a 1970 318 engine with pertronix ignition or do i have to use copper plugs for the 50 year old engine or is it safe to use the plat or irid plugs

Great video!

I have a 2015 Hyundai Genesis N/A 5.0 I am looking for a good performance plug Its pretty much stock I have a sprint booster, exaust and ram air snorkels I'm gonna get a tune soon and would like to change the plugs before then any suggestions?

You forgot to mention resistor, and non resistor spark plugs. What are the pros and cons of them.

Are non resistor plugs good to use?

I don't recall that the electrode is actually copper on copper electrodes. The conductor inside the spark plug is copper but the electrode is not. I have filed those and never found copper in any spark plug. They haven't used copper for the electrodes of spark plugs since at least the 1950s probably the 1930s because it would only last about 5 or 6,000 miles. If that.

How is copper(nickel alloy) the most common plug in 2022🤔. Why is the term copper plug still being used, all spark plugs mostly have copper cores
Nickel alloy is the conventional spark plug. Some of this info sound suspect. What is pre detonation🤔. Never heard of that.

MSD multiple spark discharge up to 3000 rpm, what engine operates under load under 3000 rpm?

hello. i have a 2015 silverado 1500 LT 5.3. Complete stock. I just bought the Blaster and Super Conductor for it, and i was wondering which spark plug and spark plug gap i should be running with this combination. Thank you!

I got 2013 Toyota Camry 4 cylinder which one should I go with 🤔

Man I need help, I don't know what's wrong with my bike! I'm running out of money and patience.

Bought it from someone who said there was nothing wrong with it, but it hasn't worked since the day I got it.

Had it for almost 2 years now and sometimes (but rarely) it works pretty much like it should and suddenly just stops working again.

I finally changed the regulator and it worked perfect!! for 15 minutes... Now it'll barley start and just stalls..

The spark plug is completely black and dry. And idk how to fix whatever is turning it black. Bike doesn't have a carburetor, so if it's running rich I don't know how to fix it. And if I need a new spark plug I don't know which one to buy.


Someone please help me!!!

The best explenation about....

2004 Toyota Matrix + recommended spark plug

I was just looking for a video like this!

Great information & to the point video...
Thanks...

All those plugs have copper cores.
They would be better refered to as nickel, platinum and iridium.
But for some reason people are stuck on calling nickel electrode plugs "copper"

Love those 340 T/A U heads, very rare!

As soon as I hear the term pre detonation I can no longer respect the information given. You cannot mix up 2 types of abnormal combustion and combine them when discussing such a technical subject. There's pre ignition and detonation..
pre detonation doesn't exist.

Good information

Great video guys. . .thanks!!!

I run TR6 NKG plugs have no problem at all. Holley knock-em out of the park. Awesome content 👍 Aussie Fan 💯🇦🇺
