Hello! It does not come with the plug wire.

Hi Joseph, thanks for initiating contact. No, it is not. This is what is called aftermarket. It has the same features and specifications as the GM OEM factory part that it replaces - without breaking the bank. If your vehicle information matches this product use the link below to order while the part is in stock. Enjoy shopping! https://www.carparts.com/ignition-coil/drivewire/rc50460007?can=CPGG4850_CSQA_20240724

Hi Toris, I'm glad to assist you. The ohm rating is not specified anymore since this is a direct fit vehicle-specific part. The ohm rating would be exactly similar to the factory's original part. For us to accurately identify the matching ignition coil for your car, please provide your complete vehicle information (year, make, model, submodel, and engine size). I hope this helps. Happy shopping.

Hi Leonard, We do not have the testing charts. We can only guarantee fitment based on our application guide. Please enter your vehicle’s year, make, model, sub-model, and engine type, and type the part's name on the search box. Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.
