It’s perplexing to maximum enthusiasts whether SP-546 same as SP-515 plugs. If I explain the stock plugs, they are much different than SP-515 plugs and broken off in the head. Mostly, they have a reasonable price. Let’s share an experience in case. SP-546 same as SP-515 plug

I had a ’07 to drive, and I felt a jerk at low speed. It was high time to replace OEM plugs for my 5.4 engine. I heard of newer SP-546 plugs then and asked my friend about the plug. I was assured of the construction as the construction was improved in smaller OD below threads. At some angle, it looks easier to put in. I compared the SP-515 and SP-546 and got them through the same OD. You won’t experience a sign of heat from any of these plugs. 

The SP-546 plugs are mostly improved in a welded and lower ground electrode, whereas the SP-515 plugs are made as one feature. Moreover, 546 plugs have a little taller porcelain. It is to be said that you will be compressing the coil spring in use through these plugs as the plugs contain a center electrode end of them. Now, it’s your choice!

Check your owner’s manual and make sure you are recommended with a fixed-gap plug or adjustable plug. Use a gap gauge to check the plug’s gap within the specified range.
