Stock Air Filter Replacement, 1973, 1974
For 1973 and 1974 Jensen Healey. K&N brand "lifetime" reuseable air filter custom made to fit the stock Jensen Healey air cleaner (the original paper unit is NLA).
Conventional paper elements are very resistant to air flow because the filter material or medium is very dense. The greater the restriction the greater the power loss.
K&N's oil-impregnated, cotton-gauze element is far superior. The process is expensive but well worth the effort. To further make the point, consider that square inch per square inch, our filter will flow an average of 50 percent more air compared to the average paper filter without sacrificing filtration efficiency.
A second and equally important attribute of a K&N filter is its ability to be cleaned. Simply wash, dry and re-oil the element at regularly scheduled intervals and it will continue providing your engine with clean air for the lifetime of your car. A K&N Filtercharger can be washed and cleaned up to 25 times. We recommend inspecting the filter every 30,000 miles or 12 months. If cleaning isn't warranted, re-oil the element to insure optimum filtration efficiency is maintained. Apply a small amount of oil to the clean side of the element.
Note: use only a special purified K&N cleaning oil kit (see below) for this purpose. Regular motor oil will ruin the filter element.
