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 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.
INSTALLING A POD FILTER IN YOUR CAR BY ATTACHING IT DIRECTLY TO THE MAFplease 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.
the above picture is of the k&n style pod filter
(note: these are not k&n brand filters)
pictured here is the hks style foam filter
(note: these are not hks branded filters)
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.
