[QUOTE=Clarky;1304184]Be careful with the K&N filters as you have to oil them. A mate of mine put one in his Hilux and the oil affected the air sensor and it had to be replaced.
I've been using a K & N for 5 years in my CRD and it hasn't been an issue.
When you oil them you must be careful not to over oil. I would say your mate has over oiled.
The instructions on oiling make this point. To make sure I haven't over oiled I lay the engine side of the filter on some clean rag and blow low pressure air on the intake side.
If there is too much oil it will be dispelled and show up on the rag.
The other thing you can do is take the vehicle for a short run then take the air pipe off the top of the filter and feel if there's any oil in the pipe.
