Bought a NGK iridium sparkplug online for Honda EG B16A DOHC, however received a sparkplug which has a longer reach than it should b. Seller claim closer to piston more power. ZTH's sifu please advice. Thanks!
My 350z's gearbox grinds when shifting from 6th to 5th. Any idea what is causing this? I read online that it is due to a faulty synchro. Anybody faced this problem before?
