I made the factory airbox on my 95 Ti less restrictive by using 3 1/2" PVC pipe and fiberglass screen. I removed the factory cone intake pipe and replaced it with the pipe. My goal was to make the stock airbox less restrictive without fogging it. It saved me the hassle of relocating the horn and drilling another hole in the airbox. Car sound healthier and revs faster. Do you think this setup is good? am I gonna break anything?? I need opinions. Thanks __________________ canadian_ti 1997 Acura CL | | | 08-17-2005, 01:13 AM | #2 | Senior Member Join Date: Oct 2003 Location: Wilmington, NC Posts: 641 | Good job on taking the baffle out of the tub of the airbox, but I think it may be sucking up more hot hair. DO you have the M44 engine? If so, that piping running across the top of the radiator sucking up air from behind the passenger side headlight would be cooler. I'm not positive about the air temp thing, but it does look like a less restrictive system. -chris __________________ 18'' Ace Wheels • Pirelli P7000 SS Tires • Bosal Brospeed Exhaust • B&M Short Throw Kit • H&R Sport Springs • Euro Clears • cat delete • Rogue Engineering Clutch Stop • Modded Airbox • blacked out kidney grilles • Suede Headliner/A Pillars S52 CONVERSION UNDERWAY | | | 08-17-2005, 01:16 AM | #3 | Senior Member Join Date: Feb 2005 Location: Canada Posts: 101 | I have an M42. MY only concern is the hot air but the PVC pipe is pointed in the same direction and sucking pretty much the same air as the factory piping so it probably isn't that bad. __________________ canadian_ti 1997 Acura CL | | | 08-17-2005, 05:43 PM | #4 | Senior Member Join Date: Mar 2005 Location: Portland Or Posts: 2,666 | The screen is more restrictive than the stock air tube was. Why the screen? If you have an air filter you don''t need it... You likely made noise not power with this mod. I wish more folks would use chassis dyno's or g-meters to test so the really effective mods could be documented. <rant mode off... > Dave __________________ Dave - PDX 1995 318ti - Active Black and Tan. 2005 330xi - Mtech 1 - 6spd - Orient Blue/Black | | | 08-17-2005, 06:53 PM | #5 | Senior Member Join Date: Jun 2005 Location: St. Louis Posts: 138 | Quote: Originally Posted by pdxmotorhead The screen is more restrictive than the stock air tube was. | how do you know this? __________________ 97 sport | | | 08-17-2005, 07:17 PM | #6 | Senior Member Join Date: May 2005 Location: England, UK Posts: 1,288 | because its like cloth over the tubing, probably causing alot of resistance..... better off putting mesh there to stop the bigger bits and letting the air filter do the rest.... __________________ 1995 BMW 316i Cosmos Black Mods: • Magnex Cat-Back Exhaust • Smoked Corner Lights + Repeators • M3 17" Wheels • De-Baffled Air Box • AC HandBrake Handle and Gear Knob • DEPO Euro Epsiloids + Predator Chronium Rings • Chrome Interior bits •IE Poly-Urethane RSFMs • Kenwood Power Series Audio • Powder Coated e36 325 Front Callipers • Sports Seats | | | 08-18-2005, 01:06 AM | #7 | Senior Member Join Date: Mar 2005 Location: Portland Or Posts: 2,666 | Take any window screen and try and swing it broadside through the air. Or try and spray water through it from 10 feet away.

He didnt put a screen on it or anything. His hole was just a key shaped hole. So far no problems on his 95'. | | | 08-18-2005, 04:33 AM | #9 | Senior Member Join Date: Feb 2005 Location: Canada Posts: 101 | thanks for the input,. ill put some mesh or just leave the hole empty __________________ canadian_ti 1997 Acura CL | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
