K&N filter in 1.9 tdi engine

[parkin21]

Has anybody used a KN filter in their standard 1.9tdi - I am thinking of buying one as over 3 years they are cheaper than buying paper replacements

go for a Pipercross or Green panel one. the K&N's are very oily as can messup the MAF Sensor.

thanks for the information - I will see what whats available. I assume that the filter part no is the same for altea and altea xl

i would guess so. Give Awesomegti store a ring they do PiperX and would give some discount as well.

Do any of these make any noticable difference in performance or economy?
Or is it mainly to avoid replacing all the time?
Seems a bit cheap to make any real performance difference.
Would it be classed as a modification by the insurance company, or just as using a different manufacturer for a spare part?

Do any of these make any noticable difference in performance or economy? - varies from none to helps the turbo spool up a bit quicker.

Or is it mainly to avoid replacing all the time? yes this is a big advantage

Would it be classed as a modification by the insurance company, or just as using a different manufacturer for a spare part? a replacement panel filter should not be classed as a mod.

My insurance company for previous cars did think it was a modification.

Performance gains are minimal to a standard car - althought air does flow more efficiently without the drop in flow a normal paper element has it gets dirtier and dirtier.

Main advantage for me is the cost - cheaper to run over 3 years than conventional filters
