Echlin is a good brand, too. You never know who really makes things these days. So many parts are made by the same company and branded for different end sellers. I just ordered a FoMoCo EGR valve for my truck. Got it from RockAuto. I had looked at the same valve branded by Duralast, and they had the same image as RockAuto, with the FoMoCo logo and same part number. It just cost more. When I got it, it was made in Mexico. NAPA still carries Echlin but they have another brand of their own, too. I believe it's BalKamp
The MAP sensor part number at O'Rielly is S595. They have another Standard Ignition part HP4470 by Standard Ignition that's $7 cheaper.
