coils price seems about right, going by what Atlantic British sells them for but price of plugs and wires you got spanked on... you could have should have bought a set of Magnecor 8mm leads for about a hundred bucks and those plugs should not have cost 2 hundred... so you got spanked. go to apexperformance.com for magnecor wires
and sparkplugs.com for bosch plugs change them yourself when you get the parts and save yourself a bundle next time its time for a tune-up....
