O2 Oxygen Sensor Angled Extender Spacer 90 Degree 02 Bung Extension M18 X 1.5

After purchasing a high flow catalytic converter I kept getting a catalyst below threshold but now no more this fixed the problem thank to guys shipping was fairly quick it took about a full week but all in all not to slow. But the threads on the exhaust side are a little tight it felt as if it was cross threading in but I think it's made to fit tight so far so good

Works great just how it should. I should have bought more

Super fast shipping. Saved me 1,500.00 for a new catalytic converter. Would buy again
