Hello! I recently purchased an 1980 Eagle and have been planning my repair/upgrade list. I got some NGK FR5-1 spark plug to replace the Champions that are currently in it. When I compared the two side by side it appears the NGKs are slightly longer and would protrude further in the combustion chamber. Was wondering if that's acceptable and what people's opinions are on what spark plugs to run if not. My first post so thanks for everyone's time in advance.

A thumbs up for your first post.  Not sure about the NGK's.  I stick with the Bosch plugs that are for our engines.

I have Champion in my 87 Eagle. Seems to do better than NGK and Bosch for my engine. Trial and error.

Stock wasn't Bosch. Should be Autolite or Champion. The FR5-1 are extended tips. See what the OEM number is on your emissions tag. 985 Autolite was also extended tip. I switched to NGK BKR6EK plugs with a hotter coil. ('70s Mopar IC12SB from Napa) and I get zero ping without my EGR.

Thanks for everyone's answers. Went with the Bosch FR9HC+. I'm doing the TFI upgrade so I gapped em to .045. I'm in Michigan so while the car is remarkably rust free (for MI), the engine needs some attention. Half the emissions junk is disconnected and the other half consists of dry rotted vacuum lines! I'm sure I'll have more questions.

I pretty much use champion plugs on everything I own now.  The only thing I use NGK plugs on now are my motorcycles and boat motors.

No, MI has no emissions requirements. Catalytic converter is already long  gone. I have a Motorcraft 2150 kit coming from Gronk and plan on removing as much of the lines as possible.

Also was wondering about the component attached to the coil circled in the picture. I'm doing the TFI conversion and wanted to know if that had to go on the new coil or if it wasnt required.  You can see my new coil in the picture.

that looks like an old "insulator"  They were used to help cut down on the electronic interference in your am/fm radios.

Yeah, that appears to be the noise suppression condenser to get rid of that annoying buzz sometimes heard on radios

More the AM than FM side. It's just an old ignition condenser put to a different purpose.

Interesting. I think I'll leave it off and see what happens. I do listen to AM radio so hopefully with more "modern" ignition components I wont get any interference on the radio. Thanks again!

sorry but you will probably still get the interference,

The instructions I got with the upgrade kit make no mention of either leaving it on or taking it off. I had no idea what it was. Guess I will have to figure out a way to attach it to the coil bracket. Thanks-I do want to be able to listen to the radio in my eagle!
