Fantastic product, relatively cheap way to add some area under the HP/Tq curve.

I bought these for my e90 328i. I put these on along with multiple other mods at the same time. Along with a 3.91 diff, stage 3 intake, revo hose, catless headers, and charcoal filter delete, these brought the car in tune with daily highway driving, when you need to get up and go these deliver!
Now that I bought an F87 M2C, I can’t wait to see how they preform as a turbo variant.

These were absolutely well worth the cost.
If I had another N52, I would be ordering another set of your MILVs for sure. On my ’06 Z4 3.0Si, while I expected some noticeable improvement, the across the board improvement and higher rev on-cam power output exceeds my expectations. In combination with a big bore throttle body (from West Coast Riots), the combination adds a higher performance character to the whole engine. With the MILVs, Peak MAF flow is ~ 250 RPM higher, and ~ 7% higher maximum (199 g/second) than the previous ~185 g/second. The improvement is like moving the whole power curve 250 RPM lower and continuing the ~ 7% increase for another 250 RPM higher than before. I can put you in touch with West Coast Riots, or look them up and tell Todd that I referred you.
To estimate power increase, if the increase is 1/2 the MAF flow increase, then 7%/2 = 3.5, 1.035 x 260hp (published stock) = 269.1hp. 1.035 x 240ft/lbs = ~248.5 ft/lbs. That confirms the power increases that your published dyno chart shows are legit.
