Our take on the DENSO Oxygen Sensor 234-3001

The DENSO 234-3001 is a heated upstream oxygen sensor built as a specific-fit replacement for select 1980s Ford, Lincoln and Mercury vehicles. It uses a 3-wire male connector, a threaded 0.708 in. mount and a 10.83 in. harness, and cross-references Bosch 13913. DENSO's OE Style line adds an aluminum oxide trap layer that shields the ceramic element from silicone and lead contamination. It suits owners of older Ford-family cars and trucks doing a direct factory-type swap; universal sensors cost less but need splicing, and this one plugs in as original equipment did.
