Overview:

The Holley GM LS7 Modular Hi-Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing LS7 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more!  The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems.  Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations  EFI fuel rails are machined for -8AN O-ring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits.  Cast aluminum construction.  Intended for use on N/A or forced induction engines in the 6.0 to 7.0+ liter range, max power at 7000-8000+RPM.

Looks terrific - great price
I needed to replace just one, but ended up using both the left and right so that they matched. In the closeup picture you can see that the original part is chrome with black on the inside edges of the fins, where the replacement is all chrome. This is only obvious up close if you're looking for it. There is also a slight gap in the fit at the lower inside corner - so not perfect, but also not noticable at any reasonable distance. Wide shots shows both replacement parts installed. As others have mentioned, this is not the same quality as the original BMW part - but at 1/4 of the price, it is a darn good value and has restored the look of my car. FOR 2003 CONVERTIBLE OWNERS: This part fits the "pre-facelift" model manufactured through March 2003. I learned this the hard way, because I didn't know about the facelift that came half a year later for cabriolets than it did for hard top models. Make sure you know which side of that manufacturing date your 2003 convertible is on before ordering.

Buy OEM
Finish is fine but sizing is wrong and these don't fit tight but rattle. About 3/4" movement in all ways, which will lead to scratched paint. If you've got a beater, these are fine but for my clean M3, I'll buy OEM from FCP or Turner.

Well worth the money!
Easy install, warm and has 3 settings. These are great as I can choose which grips I want yet always have access to warm hands in inclimate weather. I can disconnect and keep them in my dry packs. Easy pray and well worth the money. My grips are 4.125” or just over 10cm and fit perfectly.
