the prelude filter set up was decent. it was a lot more secure but the paper filter was huge and i had to pull the rubber boot around the MAF back a bit so it was under constant stress to get the filter in. it also didnt do much for 'cold' air. as i said, the new cold air version had a 5hp increase over the prelude filter version. the modifed cosmo version is pretty much identical to the carbonio except the material, and costs nearly 200 dollars less.... i like to call my intake the 'Cosmonio' i love how solid it is....i cant wiggle that bad boy at all even if i try to with my hands...man i love it when a plan comes together! __________________ 1995 318ti Active Pioneer Speakers [] Aluminum Billet door locks [] ACS Pedals/Deadrest [] ACS Shift Knob / E-Brake Handle [] Clear Corners/Tails/Sides [] Sylvania Exterior Lighting [] Custom CAI [] Dinan Engine Chip [] Dinan Transmission Chip [] H&R Race Springs [] Tokico Illumina Shocks [] BMW X-Brace [] Relocated Lighter Mod [] Custom iPod Mod http://www.cardomain.com/id/robcarync |
