PEUGEOT 106 GTi - 106 Cone Or Panel?

Q
I want to fit a performance air filter to my 106 GTi, but can't work out if a cone or panel filter is the best value for money. Everyone seems to think a cone filter is the best way to go, but surely unless it's concealed like a panel filter in an air box, it's just going to draw in too much hot air inside the engine bay? Do you have any information on the best performance air filter for the 106 GTi?

A
There are lots of arguments surrounding air filters, which means it's not always easy to decide which one is best. A performance panel filter will give a little extra bhp for very little money and if you calculate pounds per extra bhp, in most cases, a performance panel filter is usually the best value for money. A cone filter may provide a greater increase in bhp over a panel filter, but it is usually more expensive.
One of the drawbacks of a performance panel filter concerns the standard induction system, which can restrict airflow. Fit a cone filter and the air flow to it can be greater, so the engine can suck in more air. However, as you pointed out, that air includes hot air from inside the engine bay, so a cold air feed is essential. When you consider the amount of air an engine sucks in. especially at high rpm, a cold air feed often can't provide enough air to the filter. If the air filter is concealed in a box with a cold air feed, this reduces the amount of hot engine bay air it can draw into the induction system.
If you're looking for value for money, we recommend two routes, depending on your DIY skills. If you want a quick and simple solution, buy a performance panel filter. If you're keen to get your hands dirty and save some cash, buy a cone air filter and make up your own induction system with a home made closed air box and cold air feed.
