Autolite's Dave Buckshaw walks through a spark plug change

[sincereguy5246]

Some Bosch are pregapped for .43 which my 08 Cobalt calls for. Should I still check the gap or just put them in trusting the pregap?

@MarcIzKool If you think American cars are the only types of cars that have engine covers, then you obviously don't know shit about cars! And you also think that American car engines are complicated?

Here's some advice for you, don't ever try to work on your own cars engine, and leave it to the experts. Better yet, not having a car is the best choice for you. That way, if it was something you had, it won't end up on the used car market as a lemon! Go back to your little B-ball video clips kid!

[MarcIzKool23]

Why do American car makers make the engine so complicated. Why all the covers!!! No need for that, other than covering up the horrible engine underneath

[dsgb1981]

Where the heck is the distributor cap???

[TheTulsatigger]

As for the part numbers for the plugs…

X=2.0L(.035 gap) 41-108

F=2.2L(.040 gap) 41-103

B=2.4L (.040 gap) 41-103

The boots if yours are brittle or cracked are 50056-1 (replaced the 50056)

[TheTulsatigger]

Wow! Rarely do you find a professional mechanic who is this gentile with a vehicle. Some great tips in this video, even if you don’t have a cobalt. Tip, to find out which engine you have, look at the owners manual under ‘service (section 5’vechicle identification) page 5-113 & 5-122 for the 2008 model. If you don’t have the manual, the eighth (8) digit of the VIN is the engine code. X=2.0L(.035 gap), F=2.2L(.040 gap), or B=2.4L (.040 gap)

[mitsuevo8mr]

same engine founed on the cavalier and thesaturn ion, i recommend ngk and denso,i think denso are the best......

[ghando2]

why no anti seize on the plugs?

[JesusACruz64]

My engine's naked.

[frankie2234]

NICE

[eBiology]

Finally a good video... expertvillage is infecting YouTube with low quality videos and these good videos are becoming increasingly impossible to find.

[thephantomstar]

BEST!

[mystieus]

It is fairly common knowledge that Motorcraft spark plugs are made by Autolite.

Years back back ford owned the autolite name.

[1crazyJOO]

Autolite is pure garbage. Buy something else like NGK or Champion.

[obts10]

great video from a real professional. Thank you very much!

[dsouth01]

Autolite is not really the "best" plug to buy. There is a lot to be desired when looking at Autolite's numbering system(compared to NGK and Champion numbering systems). Most of the Autolite plugs you can buy today were made by the lowest bidder in China.

[EvoLar]

Now your just speculating. Autolites are made in the US. Even the box they come in is made in the US.

[dsouth01]

You obviously haven't read the fine print on the carded copper core small engine plugs at the auto parts store or kmart also see the boxes for the 4123, 3924, 2974 plugs (just to name a few). the XST series plugs are made in the states and I think the XP series plugs are too.

[oneviwatara]

Denso spark plugs are the best.

[EvoLar]

Why?

Just where do they get their iridium from?

[oneviwatara]

Because,they're the best spark plug money can buy.

[studpuppy69]

Not sure I heard Mars. Really no clue...

[Audioquest56]

The best spark plugs are the ones recommended by your manufacturer. It could be Denso, NGK, Champion, Bosch or Autolite. Choose the right plug for your car - the one listed in your owner's manual.

[oneviwatara]

Not really! I think Denso spark plug is available for every cars out there.

[EvoLar]

Thank you!

[dsouth01]

Ya, I've seen some great plugs from Denso. they're considered a stock plug for Toyota. I guess the "best" plug for an engine depends on what type of ignition system is being utilized. Other characteristics to consider are plug electrode materials, electrode design, thread diameter, reach, heat range and electrical resistance.

[lovemym16]

True the plugs depend on aplicaton, I tend to upgrade the igniton coil wires plugs cap and rotor to heavy duty part and ive had great results with an MSD high output coil and Accel-Igniton plugs and 8.8mm Wires

[dsouth01]

lovemym16, sounds like a nice rig you got there buddy. I've always used stock stuff like

Audioquest56 wrote above, but I like to try all the options too.

[lovemym16]

give it a shot! Thats just the rig i got the best performance out of. Accel-Igniton also makes one hell of a Steel-Billet distributor for old chevy and ford engines

[dsouth01]

I've always thought of Autolite plugs as low ball service parts, but I got bored and decided to give them a try on the small engines. I was surprised how well they worked (once I found one on the shelf that had straight and centered electrodes, I had to look through all 25 on the shelf to find 1 decent plug) . The automotive grade plugs look better manufactured than the small engine plugs, but who knows, you'll just have to look.

[97markviii]

You should also mention to use anti-seize when you have an aluminum head to prevent the spark plug from ruining the threads when replacing the plugs.

[dsouth01]

its weird that none of the spark plug manufacturers or auto makers recommend the use of anti seize. I always use it on plugs.
