Hey there, fellow gearheads! If you're on the hunt for an air filter that really knows how to breathe, let me tell you about the Injen Technology 8-Layer Oiled Cotton Gauze Air Filter. With a background steeped in racing and street performance, Injen has earned its stripes in filtration engineering. This isn’t just another filter; it’s been tested in the trenches—think Baja 1000 and the sandy dunes of the Middle East. If it can handle those conditions, it’s ready for whatever you throw at it.
What sets this filter apart? For starters, it’s got eight layers of cotton gauze, which is specially designed for maximum airflow without skimping on filtration. The proprietary filter oil used here is no joke either; it’s packed with advanced tackifiers that grab onto dirt and contaminants like a magnet. So, while you’re boosting your horsepower and torque, you’re also keeping your engine safe from the gunk that can cause real damage.
Now, let’s talk specs. This filter is a direct fit for many Injen intakes and even some universal applications. The dimensions are pretty neat, too: it has a flange inside dimension of 6.70" x 4.55" and an overall height of 6.65". The base diameter is 7.70" x 5.70", which means it’s designed to fit snugly while maximizing airflow. Plus, it’s 100% cleanable, so you can keep it in top shape with the Injen Pro Tech Cleaning Kit (part number X-1030). Seriously, this thing is built to last.
Here’s a quick rundown of the features:
So, if you’re serious about your ride and want to keep it running smoothly while also cranking up the performance, this filter is a solid choice. Don’t just take my word for it—give your engine the upgrade it deserves!
