I have been very happy with KnN s over the the last 30 years.
There is a perceptible reduction in restriction on most combinations. The only advice to pass on is to not over
oil the element , as it can gum up things and in a fuel injected scenario if a MAF is used, the
oil can coat the wire in the MAF and can distort the sensor readings.
You can't go wrong with K&N - lifetime filter !
