Sorry monster,I have to differ slightly-the one I got differs HEAPS from the factory one... and it's yellow!
0-100 time has dropped slightly also-same road,same time of day,same conditions.
Take a look see at a Pic of trust filter for 1G-FE
Lemme know your thoughts?I'm unsure what comes factory in th UK,but on my Altezza its a crummy,non-breathing,paper item.
