already bought my plugs/plug wires for toyota could i get a shop 2 replace them

Yes , too. I was going under the assumption (most likely a false one) that he was wise and bought actual factory parts not maxo-cheapo-junk-from-the-box.

Regardless the brand of parts, some shops will refuse to use customer supplied parts, sometimes just because they count on a big markup of parts as part of their profit. When someone brings me parts to install I specify no guarantee or warrantee on the repair and that any delays caused by a parts issue will add additional charges. Reasons: if there's a parts issue of any kind I can easily get them replaced by my supplier, but if the customer bought them I probably have to have them handle it. If the customer damages the part after buying it, and it's happened to me, I may not know it until it's installed adding more work that wasn't in the estimate. Also, I get good discounts on parts and can make extra money even without overcharging the customer. My labor rate is very reasonable and making some profit on parts helps me.
