So, Just got home from a blast out with my neighbour again. Jesus christ its quick when it wants to be. He fit a K&N filter(panel) today, Some NOS parts. We was baited by a Civic Type R. He couldn't kept up, and coming from someone who used to build them for a living I knew he wouldn't. I drove one before and never thought much of them.

Then he got shown up by a 14' 911 who decided to give us a chase which we accepted and we had a brilliant country blast. Plenty of lift off and back end happy, but held its own against the 911 until he gave up.

For a standard car, bar now a K&N panel filter I think they perform very well.
