Review on 🔥 Motorcraft Platinum SP546 (SP515) HT15 Spark Plugs - Set of 8 for Ford 5.4L - Genuine OEM by John Ramsey

The description of these candles is misleading. I thought I would buy the SP 546 forks which would replace the original SP 515 design. I got the SP 515 instead. I saw a number of other reviewers saying they had the SP 546, which was another reason I thought I'd get the SP 546. The seller appears to only stock a couple of SP 515 and SP 546 spark plugs and is selling both part numbers as if they were the same part. The SP 515's design can break when removed, and its design has been corrected by changing the three-piece spark plug to a one-piece plug.
