Could that be the geekiest thread title ever?
Think I'm going to replace my spark plugs this week, I'll check the condition they're in first but they're a few years old now and have done 25k miles or thereabouts and are pretty old.
The car's started running a bit less well over the last few days, has a slight misfire on a steady throttle which makes town driving a pain. I'm wondering if the plugs are past it.
Anyway, I can get W5DP0s for £40 ish from GSF (slightly less with the discount card) or the NGK BP7EVX which came up in another thread at £20 delivered to my desk.
Is it worth the extra cash for the Bosch?
