For sale is an excellent condition full K&N induction kit for a 1.4 ek3 honda civic.
It may fit other engines too but I cant guarantee.
This full kit allows the air filter to be mounted properly and securely (unlike the cheap ones bought from halfords).
It was around £100 new and has only been used for a few months before the car was taken off the road.
I would be willing to knock a bit off the price if you can give me the original air box off a 1.4 civic, as I will need one when I come to sell the car.
Feel free to give me a phone anytime with questions or to view.
