This weekend, along with
upgrading to 300mm vented brakes I also did some maintenance... I wanted to share some feedbacks.
I replaced the 50K miles old Bosch Platimun Ir Fusion (Iridium plugs paid about $10 per plug) with NGK V-Power (Copper plugs paid $2 each). I have to admit the car idle improved (smoother and more consistent) and some hesitation when cold is all gone... So I gotta admit I'm convinced that with plugs the more expensive plugs are not worth. There is no improvement... Maybe they'll last longer (if they actually do) but IMHO the price does not justify the investment.
I also replaced the gasket on the
oil filter housing and it went smooth... The old gasket was very dry. I also washed the engine with some degreaser and Simple Green, to check if I have any more leaks.
Here's few pix of that too
