Hello Waynne,
Yes the cat is in good condition. I would say A-1 but compare to my my Honda Accord 98 and also 2003, the cat is not a cat but a cow. I have to sale one car between the Accord 98 and the Subaru 03. I chose the Subaru for the Cargo, towing capacity, the 4x4 (the winter here is pretty hard) and the Tank side of this car, but power is not there and comsuption is higher than the Accord.
Sorry if I don't understand, but panel filter is a air filter like K&N ? Also, how do you decoke an engine? You mean to clean the trottle body ?
In other way, what do you think about the HHO/Hydrogen kit sale in Ebay . This thing can damage the engine? , ****-up the ratio air/fuel ? ...?
thanks for your time.
