Looking for advice to DIY spark plugs for 2018 Toyota Corolla LE + 2018 Toyota Hybrid Highlander
Just as the title says, I’ve tried to look into doing this myself and I’m wondering if it’s worth the money to have some professionals do it right or if this is where I could potentially save myself a few hundred. Are spark plugs difficult to DIY or is it pretty manageable / has margin for error incase you don’t tighten it perfectly?
I’ve seen folks explain the need for torque wrenches which I’m not familiar with, likewise I’m not sure where’s the best place to buy Iridium spark plugs / if there’s better Iridium ones than others. Really just looking for general advice or tips / tricks, tools that I absolutely need, etc. before I go in to attempt doing this on my own.
Thank you all in advance, I appreciate it!
