Did Spark Plugs

[MountainManDan]

Hey I'm always Trying to be Very Clean when I do Plugs - as I have seem all carbon or Grit or Debris that somehow Finds it's way
Down around Spark Plugs

Generally will Always wait for Plug Change - even If Do - Wait till Oil Needs Changing . .

I Use a Nickle Base Grease just Dab in center - biased - Toward Top . .

I Always try to Vacuum If Possible - or - Air Pressure after 1/2 Backed Out - Vac is Best ..

Note Marks on Insulator & Tips

What I have come to Note on Many Models of Cars & Trucks - 1 Thing that Owners Might Forget or
Just Quietly Fall Asleep on are Coils & Coil Packs . .


Like back in Day when cars all came with Lousy Brakes , Shocks, Wiper Blades ..

Coil Packs Lasted 150K ~ This Is NO Longer Case ~ Been an On Going Issue for some Time Now ..

Many have Not Woken Up to Very Slow Degrading of Coil Packs

What Happens is Super Slow Motion - Weaker Coil - leads to More Fuel in Oil , More Carbon Build Up
Less MPG slightly - so - Oily Carbon Deposits End up in Cat or Cylinder Wall - Piston Ring Interface . .

Rings could even Stick

I've Seen Fires Inside Catalytic convertors , Seen LSPI , Early Fuel Dilution = Why ~ Spark just Isn't Hot & Large & Fast ..

It becomes Weak , Slow Eff5 Drops way off ..

Changed out Coil Packs at 67K & 99K . . Both Perked right up & Better MPG ..

Old wives tale. If there was a legitimate ignition issue, your theory can be validated with information from the misfire counters and a check engine light.

As spark plug gap gets larger, the coils do have harder work to fire the plugs, but if you replace the plugs, the coils go back to happytime.

YMMV.

NO - Coil Packs Just do Not Perform as Designed as Cost of Copper Windings Soars ..
Vendors get Cheaper - But Mostly do to Fact They are Mounted on
Very Hot - Super Tuned Motors & most of those Now have Turbo's

Heat is Breaking Coil packs down Sooner this Sneaks Up on Owners & It Bits Hard in Pocket Book ..

Eff% on this Newer Engines Pushed to Max , when Max isn't Quite there by just Little Bit Oily Carbon Build up in Cat

Then Please Explain Why ? $3500 Dollar Cats catch Fire inside to Point of - Melting Welds Off !
.. Need Replacing on 3-4 yr Old Models
40K to 90K = Gone ..

One would Think and Yes Your Able to ~ Gap Down ~- which will Give You a Hot Stronger Gap - Spark Agree

But for How Long - Engines now Cost in Range of 12K to 18K to Replace

Not to Mention there are Higher Performance Coil Packs that Perform Better then OEM for $115 Bucks . .
Those are Heavier & Use a Higher Rated Temp. Epoxy ! ( Jump .065 ) Run Plugs for 120K

This has Become an Attempt by all Vendors Produce Coil Packs to Raise Cost to Auto Manufacturing ..

 

[MountainManDan]

Here You'll see Weight of Extra Windings - Primary & Secondary Windings in Coil Packs are Extremely Thin ..
so Little Weight = 18ft that is Equal Whole Lot more Windings inside !

More Eff% Spark Plugs - Un-Shadow Flame Front or Kernel . .
