Air filters for Series Land Rovers

The K&N will reduce restriction and improve top end power and economy.

The one down side is that the air intake 'roar' will be more pronounced (but it's not at all bad): if that's an issue you may want to skip it, but for those of us who like that sort of thing it works great!

This setup requires the stock air intake horn (permitting use of the PCV system). Simply remove the air hose leading to the air filter and fit the K&N on the end of the air horn: it's that easy!

The air intake can be pointed toward the front to allow easy access to the valve cover and permit hood clearance on models with recessed spare wheel deluxe bonnets. If in dusty conditions, simply reattach the stock oil bath filter.

On some Series Land Rover applications, where a Weber 1 barrel is fitted, it is possible to fit a K&N directly to the top.

NOTE: You will need at least 3.5 inches from the top of the carb to the bottom of the hood for clearance. Also plan to rejet the carb (richer), since they are not designed specifically for Land Rover applications and were not correctly jetted right out of the box: exhaust valve damage could result if you don't!

We do not recommend the use of the plastic isolator block so that the carb can get some heat through the manifold.

The K&N filters come pre oiled and ready to use, and will go a long time before the first service is required (under normal conditions). Many folks like to go ahead and get the service kit, just to have it handy, plus it's a bonus if you're on a trip and you need to wash out a dusty filter. The instructions for cleaning are provided, and even if you aren't known for your prowess as a mechanic you can easily do this. The kit comes with a cleaning solution and special oil (NOTE: never use motor oil, solvent, or transmission fluid to re-oil a K&N filter: it won't work!). The kit is good for several cleanings.
