Top brand top performance.
David Maidment, West Down, United Kingdom
Have used this filter on my VW T5 Transporter (102bhp)...well pleased with my purchase...whilst there is only a small improvement with engine performance for what it costs, this air-filter is worth every penny. And it is so easy to fit!
Matt Palmer , Portsmouth, United Kingdom
Excellent air filter 5 minutes to fit and it does make a difference.
