Well, missed out on a set of SVO heads for a decent price, so I did the next best thing and purchased a tick flow plenum. OK, I know it's only a worth a few hp, but have to say that my first impression is that it goes well with the improved breathing of my NPI heads that have the PI cams and PI intake. I'll also have it when I eventually do get a set of heads. It's quite a bit higher than the stocker and it's a tough fit with the aftermarket TB tube. I'll have to revisit it to see if I can get it to fit better. Snapped a few pics going in....FWIW, it's the powder coated silver version.
