OE Style Design Details
The Denso OE Style line is built and tested to OE standards, with precision construction for first-time fitment. This sensor also uses Denso’s aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable engine operation and long service life. This part cross-references Bosch 13747 and Standard Ignition SG858 for the same application.
