There's some question as to whether or not the side intake scoop on the Gruppem will bolt up nicely. Theoretically, all the rest will, as they leverage mounting points originally intended for common parts.Might be a stupid question, but are these intakes for the FL5 all direct fit for the DE5 also? That Infinity Design looks pretty darn solid.
Interesting. I wonder what about the PRL leaves it far behind the rest of the (way more expensive) options.For a closer look at the charts, check out the blog post version: https://www.tegiwaimports.com/blog/?p=7444
Looking at the P-norm curves, here's my rough attempt at comparing the powerbands

Nice find! I will link on main page
Some of the other options replace the OEM rigid plastic section that bridges the inlet pipe to the intake. PRL doesn't offer a replacement for that section and I wonder if that obstructs some flow.Interesting. I wonder what about the PRL leaves it far behind the rest of the (way more expensive) options.
full disclosure: I haven't watched the video
I feel like even a small leak would be a noticeable change in drivability, and throw codes.Installed the PRL HVI and I hear a sort of whistle/high pitch whoosh sound during induction mid-high rpm range right before the typical higher pitch turbo sneeze/whoosh at shifting.
Is this normal or do I have a leak somewhere? I already made sure all my connections/couplers were tight though.
Blackhawk is very interesting. Check out some of their wheels. I think some of it is offset by shipping/customs, but ~$600 a wheel for forged 19" Volks is insane. That's 50% off anywhere else I could find online. Seems too good to be true.After shipping, 4.3% import tax, and whatever state sales tax applies, this seems to be a much better price than I've seen from anywhere else:
