    Yup. K&N, Pipercross or other similar washable performance air filters have always been a good investment. K&N tend to be a bit overpriced as an alternative, but other performance filters like Pipercross aren't necessarily more expensive than the cost of a genuine OE paper replacement...but besides the significantly improved airflow which gives an increase in both power and torque, you only buy a performance filter once since it never needs to be discarded and replaced like the paper OE style filters.

    I fitted a Pipercross performance filter from TerraFirma in my 2017 3.0L TD6 to replace the bulky and inefficient folded paper OE air filter. It's the first thing I replace on any vehicle I've owned...did the same on the D2 and the D4.

    I tend to favour Pipercross over K&N...but that's just personal taste as well as the eye watering price of K&N filters. Outside of that, there's nothing to pick between the 2 brands other than cost and availability.

    Links for a couple of options below, but performance air filters are readily available from most specialist 4x4 online stores, so you might find them a couple of quid cheaper if you search around. Thumbs Up

    Pipercross (TerraFirma) performance filter

    Since you have the 2019 3.0L SDV6... which I think has the twin air boxes?.. I'd suggest this great quality option from BritPart...both replacement filters supplied in the box. No pre-oiling required...just wash with detergent or blow out with air once a year.

    BritPart easy clean performance filter (Pair)

    Both of these options are straight replacements for the D5, just remove the OE paper filter(s) and stick the new one in. Washable or easy clean performance air filters are definitely a sensible step up from the OE paper ones...30% more airflow than a paper element as well as a lifetime guarantee so like I said, you only buy it and fit it the once.

    In the case of K&N or Pipercross filters, just remove, clean and respray with additive once a year and put them back in. Wink

    K&N also do washable cabin pollen filters for the D5...Like all K&N branded stuff...a bit overpriced, but again, a buy once lifetime guarantee.
