yah, it is my daily car. After taking off the intake system, changing the spark plugs is easy one.

Can you provide more pictures? I just want to check the condition of my plugs. Is it possible to remove one of them without disassembling the intake system? Just coil and plug?

Thanks for the pictures. What do you guys use to clean that up? Obviously wiping it first, but spray it with TB cleaner? (seems like the universal cleaning agent). Just a bit worried of stuff falling through the valves.

Thanks,
