Mil eliminator question...keyed?

[Str8Kr4zy]

Are the left and right O2 sensors keyed to their respective side...if so, is it safe to assume that if I ordered a set of mil eliminators, they should be as well?

I purchased a pair and the driver side hooks up easy, no problem. Passenger does not. The notches on the mil elim and the o2 sensor differ.

I'm thinking I received an incorrect one, either different year model or just two driver side elims.

Any thoughts?

Thanks guys!

They are keyed from the factory. Normally the keying is for the front/rear O2 sensors. But they are interchangable on the Mustang.

Just file/cut the key tabs off.
