First off, I need to know what that little black and grey round thing is just to the left of the arrow. Mine's got a hole in it. Anybody got a part number or at least a name???
Next, I'm about to change my plugs. I've got the 3 tipped densos. The dude at Autozone says they shouldn't be gapped, but I don't trust him. How do you measure the gap?? He says you measure from the tips to the ceramic. He said you can't even measure that on a triple tipped plug. Last time I put them in, I measured from the tips to the center electrode. Was I doing it wrong?? This has got me worried.
Third is for you suspension gurus. I've noticed today that when I'm in a slow turn and hit a light bump or something, I'm hearing some popping/cracking/unusual sounds from the front left. I'm on stock suspension at 85k miles. Should I be worried about this too?? Maybe it's time for some upgrades, but not unless my other is shot.
I'm about to get chipped, so I want to be in tip top shape. Any help on any of these questions will be GREATLY appreciated!!!!
