Fits Porsche 993 Carrera 2 / 4 Porsche 993 S / C4S Porsche 993 turbo This oil backflow kit incorporates a check valve between the oil tank and the engine which prevents the smoking on start up for naturally aspirated and turbocharged 993 models.
Perhaps you have installed a pressure side oil backflow kit on your turbo model but are still experiencing smoking on start up. The issue may be on the suction side. The problem on the suction side is due to the oil tank sitting higher than the engine oil pump. Gravity creates a positive pressure on the pump and slowly fills the engine case with time. The case fills up and eventually pushes oil into the catch tanks on the hot side / turbine side of the turbo charger. Once the car is started, the cars smokes very heavily which is often misdiagnosed as a defective turbocharger.
Sold individually. 1 necessary per car.
Recommendation: This kit is all that is necessary for naturally aspirated models.
It is best to address both the suction and pressure side to prevent the issue entirely on turbo charged models. We also sell a pressure side backflow kit under part # 993113320

9m 718 2.0/2.5 spin on oil filter adapter kit
Spin on oil filter adapter kit specifically developed to eliminate any potential failures of the the OEM paper filter element which is prone to breaking down and the fibres of the filter and can cause fragments of the paper being sucked into the engine which will cause engine failure or faults that require engine strip down.
This kit is to adapt the standard paper oil filter cartridge to a conventional metal screw on canister filter setup.
Highly efficient and a huge improvement over the standard paper unit, providing much improved oil filtration.
Together with regular service intervals can prolong engine life.
Kit includes
Threaded spin on adapter plate constructed from clear anodized, 6082T6 aerospace grade aluminium and OEM type, high quality metal canister oil filter with built in pressure relief valve.
Easy to install - simply remove/unscrew the black plastic cone shaped original paper filter housing, and replace with/screw in our adapter plate. The new canister oil filter then simply screws onto the threaded nut in the centre of the metal plate no more messy oil changes draining from the plastic spout.
