Se monte parfaitement en lieu et place, le moteur semble respirer bien mieux.

Excellent service over the years. Every vehicle I buy; bike, car, or pickup, the first thing I change is the air filter as standard filters dont let enough air in. I think these filters are quality products and fit perfectly.
