2001 RX300 with 1mzfe engine, 137k miles(or 220k km)
Still the original spark plugs.
I have the new set on hand, but I'm concerned on how hard it'll be to loosen them.
Front 3 are easy with wide access.
Rear 3 are hard to get to, don't want to take the intake plenum off.
There is a way to go from either side, but nonetheless, will not be able to see the condition back there. Mostly done by hand/feel.
I know the longer they're left in, the harder it is to take out without issues. I also saw some suggest to spray pb blaster or penetrating oil. That's easy to do on the front, but not the rear though.
Should I attempt to change the front 3 first and see how they look?
If they're hard to get out, the rear is probably just as hard and leave the rear 3 to a shop or something?
Even though, I don't know if they will do it any better.
