Just changed the plugs on mine @ 75k 2 weeks ago. DIY EASY! Installed the NGK Laser Iridium ILKAR7L11 94124 plugs. Old ones screwed right out.
I change spark plugs - I change my plugs every 30,000 miles spend the extra money for NGK.
Only ever buy ngk plugs and learn to read their reference chart then you will always know what plugs you can/can't use for small engines
Personally I gapped my NGK laser iridiums to .024 and I've had no issues what so over, I did however have issues with the OEM spark plugs when I pulled them out to which they were gapped at .054, which OEM spec is technically .034
I swear by NGK
These are good plugs Autolite my mechanic recommended them to me good spark and seems like my truck is running smoothly and there a good price.
Apart from that, NGK is my go-to brand for everything they make.
So, I changed spark plugs in an old Ford Focus 2001. And currently there's no way I can get the original Motocraft spark plugs, so I bought and installed the NGK ones which are supposedly compatible with my vehicle. I used them a week, but since the start I noticed great differences in size in the threads and in the shape of the head. Is this a problem?
Just replaced the OEM ones with the NGK PLFER7A8EG 94833 as part of my 40k service on the car. Pretty straightforward like usual except the hard part is maneuvering the coil pack connectors that rest again the intake pipe because of the plastic covering that thing was such a pita. But now the car feels like heavy, like when you put on some heavy wheels on and you can tell the difference right away. I've been having to be so light in the gas pedal because it would fly. Now it feels like I really have to push the pedal a lil harder then usual to pick up speed but it just feels heavy kind of (not sure it's the best description) but it's it not hesitating at all.
I replaced the spark plugs with NGK Iridium IX factory gapped to .044". Everything went smoothly, reinstalled coils, air box, battery, connected MAF, and started the car. Now it is shaking, smoke coming out the exhaust, and blinking check engine light.
