The proper plugs have 3 prongs and should come gapped correctly. I didn't see any specs in the manual so I assumed this was not required. I'm not even sure how I would gap a plug like this.

Anyone over 70k just replace their plugs? Curious what they look like compared to OP post.

The key I've found for these is to have the perfect combo of extensions, mix and match a few super short stubby extensions until you have the ratchet right where you want it.

i havn't had any problem with my spark plugs yet. also im doing new injectors \o/ yay

Mine were pulled below 50k miles and they looked pretty awful, made me wish I had that taken care of a bit earlier. I probably won't go more than 30k on the current set. I'd rather pull them too early than late to understand a good range of when to change them going forward.

I have them around somewhere for future comparison. And pictures if I remember.

They don't look bad, actually. A bit of carbon closer to the threads, but the firing surface is clean and the electrodes are a nice tan color...thanks for posting that pic.

Yea not too bad, those look 'normal' for 66k.

On another note, I stopped by the Subie dealership for some OEM oil filters.. asked the serviceman about changing the spark plugs, he said they won't need to jack up the engine when changing the spark plugs. Not sure if that was just a sales pitch, but I'm sure they're not the only mechanics to take "short cuts" when doing maintenance/repairs.

@Black Tire

In the 355s defense, that's because it was one of the last ferrari's to have an interference engine with a timing belt, so if the belt failed you'd have a piston smash the valves. Most of the modern stuff like the Califronia T, 458 and 488 go much longer between those engine out services. The 458 for example only needs a major 5-6 year service regardless of mileage and only a 20 hour job vs the 50 hour job the F430 had.

Dude it is Subaru. They are used to changing plugs on boxer motors.

It doesn't matter how used to you are changing plugs - it's a matter of how little room there is when you don't jack the engine up.

So far OEM. It's not cheap though. $22-25 per plug.
The plus side they last a long time.

Will have to rethink this 60,000 mi service thing! Just got a call from the dealership and it was going to be $750 for this service

. At least they were nice enough to call! Needless to say I said thanks but no thanks!

Will have to see about the plug change when it gets a little warmer here.

Cheers.
