I'm having the timing belt & water pump replaced in a week, along with valve cover gaskets, and would like recommendations of any adjustments. So far I've ordered a Gates timing belt kit, Felpro valve gasket kit, Beck Arnley 192 thermostat and gasket, and am considering which NGK plugs to get. The recommended plugs on the NKG website and prices on Ebay are as follows:
2262 ~ copper ~ 2.59
7098 ~ platinum ~ 3.24
4363 ~ platinum ~ 9.04
2477 ~ iridium ~ 6.25
My objective is mpg, and I'm tending to the 7098's but am open to any of the upgrades. The site states both the platinums are good for fuel economy but doesn't state the same for the iridiums, just saying fuel efficiency, whatever that is.
Regarding the timing belt, should I have them stick with the OE setting? I'm quite happy with how the car's been running to this point. I'm going to have them check the head gasket too, though I never need to add any coolant. I'm tending to change the distributor cap & rotor too. I'm interested in any ideas as this is quite a bit of work to be done.
