spark plugs

I havn't done it myself yet, but it will also depend on what tools you have.

The Service Department at Santa Monica Subaru told me something similar.

Can't be any worse than a 4th Generation Camaro...

And seriously, more effort compared to an I4 for changing the spark plugs would keep someone from owning this car? After a test drive and getting some seat time with one you'll change you mind... "This isn't a normal handling car - it's a sublime and exotic handling sports car that stock feels better than modded "sporty" cars...

Just need rachet extensions

This car has Iridium spark plugs. They don't need changed until 60-100k miles unless you plan to heavily modify it into a different heat range. And if you plan to modify it, you have bigger things to worry about. If you don't feel like changing them yourself every 5-10 years, then have a mechanic do it for 50 bucks.

It's ridiculous to say you don't want this car anymore based on the spark plug location!

Say what you want about BMWs and maintenance, but at least on the older ones they did a great job of putting every right where you wanted it for maintenance. Even the oil filter was remote mounted right up in front of the engine so you could replace it standing over the car.

Ya, I read that you had to jack up the engine too. That is crazy, but we will have to see if there is a way around that.

Also for those looking to change the plugs out to something colder, that may not be something I would do right away. These direct injection engines are super picky with their spark plugs. A shortened electrode can cause misfires, too cold and misfires. It may not be something to mess with for a long time.

Probably no more difficult than the rear plugs on a EZ30 Subaru engine, now they are HARD to do.

The EJ20/25 SOHC engines are the easiest thing on the planet to change sparks in, DOHC WRX engines a bit more work

Changing the coils on my 2.8 Saab 9-3 was horrible. In order to expose the rear bank, the intake manifold needed to be removed and the purge valve, which is incredibly delicate to handle. Once removed it was still a struggle to get them out. There was such little room to move.

I am amazed at how much room is in the engine bay of the FRS/BRZ.

These are a load of fun, especially with 1/2 the engine under the dash.
