So I recently have been thinking about throwing on a 3.7 TB on my Type S. I most likely will do it, along with a P2R IM spacer and gasket. My question is; Can someone explain to me what Boring and PnP is, effects, pros, cons...I am very interested in that, for I want the most free flowing and breathing exhaust for my car. Currently I have P2R intake spacer, AEM V2, Rv6 jpipe, Dynomax, Magnaflows. Soon to upgrade by getting the PCDs, TB, and IM spacer...anybody have any good break downs about the boring and PNP? Thank you!

 

read all 28 pages and you'll have a great idea of what to do and what you can do. it sounds like a lot, but it's a great way to educate yourself and make the right decisions.

Dont waste your time on a TB spacer or intake spacer, they honestly dont do much for the money you spend on them.

Upgrade to the 3.7L 2012 TL SH-AWD intake manifold, porn and polish your lower intake runners and do some research on the TL/ZDX Throttle body.

 

Someone's been watching too much " porn " .... Polish .....
