This is what K&N claim.
K&N’s replacement air filters are designed to increase horsepower and acceleration while providing excellent filtration. We make over 1,200 different replacement air filters for virtually every vehicle on the road. These filters are washable and reusable and are custom designed to fit into your existing factory air box. Their drop-in design means adding performance is simple. With most vehicles you simply remove the disposable air filter and replace it with a K&N. See applicable instruction sheet for details. Our stock replacement air filters for street vehicles are covered by our famous K&N Million-Mile Limited Warranty™ and will be THE LAST AIR FILTER YOUR VEHICLE WILL EVER NEED.
A million mile warranty – hmmmm… Ok I’ll give it a go – ordering it from Amazon – this is the one if ur interested in getting one for your Astra
The media says that Australian Retailers are struggling with competition from online retailers… well all i can say is if brick and mortar retailers can knock their prices down to the same as online retailers I WILL be in your shop in a flash!!! But if I can save $30 to $40 by buying it online – what do you think I’m going to be doing??? I can go on more about Brick and Mortar Retail vs Online Retail but I will leave that for another day.
This performance air intake also looks interesting – may even have to buy this one down the line.
Paid for the air filter today – now have to wait for 7 days…..
