I have a 1985 BMW 535i 6cyl with a 3.4L. Bought a WK81133 from Car Parts.This catalytic is for a 3.5.  I had it installed in my car and still did not pass the smoke test.I have done every thing necessary to make it pass. My mechanic wants to know if it makes a difference the 3.4 and 3.5. Also is this catalytic is a 2 phase or a 3 phase? Very important. Please get back to me I need to resolve this issue. Thank you for your service.carlos s.Oct 07, 2021
Best Answer:Hi Carlos, I'm glad to assist you. Please provide your complete VIN number so we could double check carefully. This is a semi-universal type (that need welding) and a 50 state legal catalytic converter. This fits only a 3.5L engine with California emissions. I hope this helps. Happy shopping.
