The TB openings are bored out to work with a 58mm TB. The runner openings are siamessed for SLP runners and opened up to work with all aftermarket runners. All work is proffessional done. The TB openings were smooth out and blended inside. This plenum has been blasted inside and out, all threads are good and have been chased. No fittings with this plenum. $200.00 FIRM shipped. If you have the money now and use Paypal you go to the front of the line. E-mail me for pics. Thx.
