Can you fit a high performance air filter to a ford escort Mk6 1.3L HCS engine?
You can put a “better than stock” filter on any vehicle. I suggest a K&N filter since it has better airflow and you can clean/oil/reuse it plus you will always increase horsepower. Go to the K&N website and search for your car’s model. If one is not available, measure what size filter will fit you application and buy it by size. I have designed custom cold air induction systems for many cars and I usually buy the largest that will fit where the air box was.
