i know i need the denso pk16pr-L11 plugs, the last time i bought them they were around $7 each, now my service center wants 12.69 each. anyone know of a good place to get these things any cheaper?

I get mine from sparkplugs.com. About $7/each + shipping.

Another interesting source is Amazon.com, that has them for $6.82 each, and no shipping charge if you buy 6 (no shipping on orders over $25). I may go there next. I buy Purolator oil filters in bulk from Amazon at excellent price.
