Way I see it is that if I can get more, cooler air into the engine then the ECU will inject more fuel to maintain the mix and that will increase the BHP and torque.
Iv e only found one induction kit for the DCI which is the K&N 57i and this comes with an open cone and a cold air feed fed from the front of the car. Which, if I fit it I am going to replace with a heat insulated feed and remount it so it doesnt travel across the engine as the original one does. Im hoping to take an intake from the left hand side straight to the filter. However the way I see it this will only produce cold ai in the vicinity of the filter when the car is travelling at a reasonable speed. This would mean that from standstill the new filter, although less restrictive, would draw in warmer air than the factory box.
As no sealed IK is available that led me to consider the second option, which would be cheaper also. That is to remove the Renault air pipe and run a heat resistant pipe from a similar point at NSF of the car, Im thinking of fitting a round intake in the lower griller area, and running it to the factory box. Then replacing the Renault air filter with a K&N panel filter which should also be less restrictive. The problem I forsee here is that although the set up will provide more air and it will be cooler - from standstill - it will still be more restictive than the IK including from standstill.
Thus it is a matter of what has most effect - air temp or air flow and whether the IK can be heat shielded in some way.
Has anyone got a diesel and fitted an IK and if so how did you find it?
People with petrol cars please dont plaster the thread saying I should have bought a petrol car. I like Diesels.
