usually the very first performance mod anyone ever makes to their car is the high flow performance air filter, as its usually the cheapest & easiest mod to perform. the idea behind high flow reusable air filters is that they allow more air to enter into the cars engine, which promotes better combustion rates, and therefore more power..

here is a quick speel from the k&n website. k&n are regarded as the best performance air filter manufacturers in the world.

For over 30 years we’ve manufactured serious air filters completely unlike traditional disposable filters. Our air filter is designed to achieve high, virtually unrestricted air flow while maintaining filtration levels critical to ensure long engine life. The secret to our success lies in the unique characteristics of our filter medium that was originally developed by K&N all those years ago in the dust, sweat and tears of desert motocross racing. We just wanted to win races and stumbled on a cotton filtration technology destined to be great (by the way there is no truth to the story that the first K&N was made from the blood soaked bandages of a racer left for dead somewhere outside of Las Vegas). Our high flow cotton gauze air filter is washable, reusable and built to last for the life of an engine. The filters consist of four to six sheets of cotton gauze layered between two sheets of aluminum wire mesh. This media is then pleated and oiled to enhance its filtering capabilities and overall performance. The result is an air filter that allows dramatically more air into an engine, is washable and reusable, and will protect your engine for the life of your vehicle.



POD FILTERS

pod filters are probably the most common form of aftermarket air filter available. there are many different types, and many different manufacturers. there is the cotton k&n type, which comes in many different sizes and similar styles are made by many different companies, such as simota & others. then there are the foam style filters, the most known of which is the hks range of filters which are often seen in the engine bays of popular jap imports. similar foam style filters are made by companies like finer filter (the o2 rush filter) and others.

(note: these are not k&n brand filters)

INSTALLING A POD FILTER IN YOUR CAR BY ATTACHING IT DIRECTLY TO THE MAF
please note, this is the easiest method you can use for installing a pod filter. it retains the base of the stock airbox so that you can fit the standard panel filter down the track.


what you will need:

maf adaptor plate for a nissan pulsar/silvia/200sx
a pod filter with a 3" rubber adaptor
4 x 10mm threaded bolts with nuts to suit (or bolts from original airbox with nuts to suit)


first up, the old air box has got to go. undo the 4 clips on it, 2 on each side,  you need to take off the 4 bolts that keep the box connected to the maf.

there is a sensor connected to the box.  it is secured with 2 screws into the upper left of the box.  undo the 2 screws and pull it out. now the top of the airbox should easily be removed from the engine bay.

put the maf adaptor plate on the maf and secure it with the nuts & bolts.  tighten it all up

put the pod filter on the maf adaptor now. there should be a hose clamp on the rubber adaptor of the pod. this will slip over the maf adaptor snugly. you then need to tighten the hose clamp so that the pod filter wont budge. and that’s it, your done.



PANEL FILTERS


panel filters have the same high flowing properties as the pod filters, the difference is that, they are a direct replacement for the factory item, and you will no have to remove any part or your cars intake setup. installtion is simple, as it is just like fitting a replacement filter. this tends to be the most popular option for pintara owners.

another advantage of purchasing a high flow reusable filter is just that, they are reusable. unless the filter is damaged somehow, you should never have to buy another air filter again.

the first thing you must do is to ensure that your filter is a reuseable cotton based filter, and not a cheap paper element pod/panel filter. please note that, simota pod filters are in fact cotton based filters even though they retail for $40. they are pre-oiled from the factory. also note that, k&n filters ARE NOT pre-oiled from the factory. you must oil k&n filters before you begin to use them.

HOW TO OIL REUSABLE AIR FILTERS

what you need:

k&n or similar recharger filter care service kit (retails for $25, available at most automotive stores such as autobarn)

pre cleaning -

gently tap the element to dislodge any large embedded dirt, then gently brush if needed with a soft bristle brush. (note: if complete cleaning is not practical at the time, re-oil the element and re-install in your car)


spray on cleaner -

spray k&n or similar air filter cleaner liberally onto the entire element and let soak for 10 minutes.


rinse off -

rinse off the element with low pressure water. tap water is ok. always flush from the clean side to the dirty side. this removes the dirt & does not drive it further into the filter. (ie. flush in the reverse direction of what the air would normally flow)


aeresol oiling -

after cleaning the air filter, always re-oil before using. spray k&n or similar air filter oil down into each pleat with one pass per pleat. wait 10 minutes and re-oil any spots still showing.


reinstall -

re-install your pod/panel filter element with proper care. make sure that the element seats properly in the filter case/correctly mounted onto the maf adaptor. install the cover (if required) making sure its in the correct position. tighten all the nuts/clips to factory specs.


reusable filter use/cleaning hints & tips

its an idea that, if you purchase a k&n filter to only use k&n filter cleaner on your filter. k&n filter cleaner is also usable on many other brands of reusable cotton based products.

DO NOT clean your filter with petrol of any kind.
DO NOT steam clean your filter
DO NOT use caustic based cleaning solutions on your filter
DO NOT use strong household/automotive detergents
DO NOT use a high pressure car wash hose on your filter

any of these items can cause harm to the gauze filter media, plus it will shrink the rubber end caps/adaptors


drying hints

always dry your filter naturally. after rinsing, shake off all excess water and let the element dry naturally.

DO NOT use compressed air
DO NOT use an open flame
DO NOT heat dryers

heat will shrink the cotton filter media. compressed air will blow holes in the element.


oiling hints

never use a cotton based reusable filter without it being oiled first. (the filter will not stop the dirt without the oil) use only k&n formulated oil on your k&n filter. this oil is also usable on other brands of reuseable filters. k&n air filter oil is a compound of mineral and animal oil blended with special polymers to form a very efficient tack barrier. red dye is added to show just wheer you have applied the oil. eventually the red colour will fade, but the oil will remain and filter the air.

NEVER USE AUTOMATIC TRANSMISSION FLUID
NEVER USE MOTOR OIL
NEVER USE DIESEL FUEL
NEVER USE WD-40, LPS OR OTHER LIGHT WEIGHT OILS



performance hints

service every 50,000km (most people will recommend to service every 10,000km) on street driven applications. service more often for off road applications or in heavy dust conditions.
