What's up friends? I commented, I'll start to improve air inlet my astra 2.2, and I have several options: the first is to keep the entrance I had before, pipe 76mm with Pipercross replacement filter, but changing the filter with a K & N .
the second, a little more complicated: lead the trunk drums, to use all that space and thus bring weight to the rear, that would place space a half-open of sheets of genuine carbon box, not imitation xD, with a filter conical K & N, and a pipe of 76mm, all well insulated, and of course, with an air inlet directly from outside.
How do you see the 2nd entry? do you think that will not suffer losses at low or at high rpm? Thanks for the attention
