VIRGIN Puro P1 PL20195 CUT OPEN

[Sayjac]

Not too good. This one made Nov 2013, older stock with hole centertube. As opposed to the last three P1/PL anecdotes posted recently run ~9-12k miles, a couple two ocis, on newer stock and no drama. Just sayin.

What the cuts in the ADBV also show is that the base inlet holes are partially covered/blocked, which could cause added flow restriction and added delta-p.
