Q:Fit a 2016 Ford Focus se?
Ayden T.
A:BEST ANSWERHi Ayden, I'm pleased to assist you. This is a universal kit not a direct fit for the 2016 Ford Focus SE. We do not have the compatible exhaust manifold compatible with the vehicle. You may want to consider purchasing heavy-duty cleaning industrial-strength wipes, good to have around your home and garage. Click on the link below to see and order while supplies last. You'll get a 30-day post-purchase price match guarantee with your order. I hope this helps.

Q:Will this fit an 08 impala 3.9l V6 doesn’t specify for v6 or v8?
James B.
A:BEST ANSWERHi James, I'm glad to assist you. No. These are not compatible. We currently don't carry direct-fit exhaust manifolds for the 2008 Impala 3.9L models. We suggest checking the local part stores around your area or the nearest GM dealership directly on what they have available to offer you. I hope this helps, and we thank you for inquiring. Show less

P0042 Code: HO2S Heater Control Circuit Bank 1 Sensor 3
P0042 Code: HO2S Heater Control Circuit Bank 1 Sensor 3Bank 1 is the side of the engine where the #1 cylinder is located. P0042 code is set when your car’s PCM determines a potential problem with the heater element circuit of the oxygen sensor.
P0058 Code: HO2S Heater Control Circuit High (Bank 2, Sensor 2)
P0058 Code: HO2S Heater Control Circuit High (Bank 2, Sensor 2)Many oxygen sensors also have a heating element that helps bring the sensor up to operating temperature quicker. These sensors need the heating element because they produce more accurate readings when brought up to a certain temperature. Once the sensors are up to operating temperature, they send exhaust oxygen data
P0080 Code: Exhaust Valve Control Solenoid Circuit High Bank 1
P0080 Code: Exhaust Valve Control Solenoid Circuit High Bank 1On vehicles equipped with variable valve timing (VVT), the PCM can adjust the camshaft position, altering the timing of the exhaust and/or intake valves. The PCM controls the camshaft position by regulating oil flow (via a solenoid) to the actuator(s) mounted on the end of the camshaft(s).
P0411 Code: Secondary Air Injection Incorrect Flow Detected
P0411 Code: Secondary Air Injection Incorrect Flow DetectedAs was mentioned, the secondary air injection system reduces emissions by introducing fresh air into the exhaust system. Older vehicles have a belt-driven air pump while newer models have an electric pump. Code P0411 may get registered when the amount of air entering the exhaust is not what the powertrain
