You're basically paying for the OEM connector on some of these.If you're not super anal, you can always get a Bosch 4 wire universal for under $40 and splice in your existing connector. I've done this on my last 3 cars without any difference.
here's some more incentive to go w/ bosch. $10 prepaid gas card.http://jobs.boschusa.com/AutoParts/Promotions/GasCard/
