## Description

Replacement air filters for street vehicles come with a lifetime limited warranty. Other air filters come with a one year limited warranty.

Review: A performance air filter you don't have to oil - I have a VW Touareg 3.0V6 TDI (2012), which is a great car in many ways, but has a known design fault regarding its air intake system. Online forums such as mytreg.com have revealed potential for water to enter the air intake box, soaking the paper air filter, and in some cases leading to paper particles being ingested into the engine, destroying turbos, and even causing engine hydro-locking. The design of the main air intake, and possible blockage of two water drains, is the main issue. Regular checking and clearing the water drains is one way to prevent such damage, but additional protection can be gained by using a paperless air filter that is impervious to water damage, and can also be cleaned/reused. I'm not personally convinced of performance advantages from such filters, but in this case the safety factor is more important. This AEM filter is a development of the well-known K&N brand, but doesn't require re-oiling after cleaning - a potential for damage to MAF sensors if done incorrectly. It comes direct from the USA, so delivery may take up to 2 weeks, but so far I'm well pleased by the filter's quality of construction and fit.
Review: Fits perfectly - Great oil-less alternative to K&N, although owned by K&N, just wash & go!
