Hi - anyone using the Dinan High Flow Air intake? Fairly inexpensive @ around $200 and its actually a modification to the stock airbox.
The engine in the 2003-2005 non-M E85 Z4s is an M54. You still need to get the CAI for the Z4 because the air boxes are different between the E46 and the E85.
I was able to take the Z4 on a 150 mile run this weekend on both the highway and twisty roads and I'm very happy with the Dinan airbox. The car is a bit more throaty, but not intrusive at all, and I definitely feel like its a bit smoother and more eager to accelerate throughout the acceleration curve.Thanks! Interested to hear a longer term report too.
Id be interested in seeing a pic of the Dinan installed? What is the model # of the Dinan? Lastly what year is your Z?I chose the Dinan for 2 reasons. It maintains a closed (pressurized) air box that gathers air from the stock ducting. At some point I'll probably add the ram air tube to increase flow. Other systems basically suck in air from the engine compartment to one extent or another.
Also the Dinan is 1/2 the price of the afe and since I don't believe that either system will actually provide more than a few hp boost, I'll save a few $$.
Man that looks nice!Its the Dinan D760-0011 and it's designed for Z4's equipped with the M54 engine. Won't fit on a 3.0si. My car is a 2005 Z4 Roadster with the 3.0 engine.
Looks like this installed.
Unfortunately true.Man that looks nice!
Thanks for sharing the pic. Its a challenge finding good aftermarket parts for the SI.
Not fond of AFE or K&N, i'm going to keep the stock intake.Unfortunately true.
I believe Afe is your only choice for a full CAI assembly for the 3.0si, but K&N makes a high flow filter for the stock air box.
Just not enough 3.0si's built, and even fewer 3.0si owners interested in making mods for aftermarket manufacturers to invest in development.
If you're looking for an exhaust system, be prepared to firmly grasp your ankles, as Eisenmann and Super Sprint are the only sources. After a lot of research I did the muffler delete for about $300 and really like the result.
The quantity of Z4M's built was smaller but a high percentage of those owners mod their cars so at there's more choice for them.
