Hi guys,new to site.I have a 1995 525i very clean and runs great.My problem is that it sounds like the manifold is leaking when I step on the gas but does not leak.Also want to do tune-up,what plug brand is best or tune-up kit?

[Jack Dabsy]

Which engine does she have, M50 or M52?

[Bockbmw]

its an m50 motor.Also how about tune-ups?

[Jack Dabsy]

M50 - You've already got a better manifold and TB than the newer M52 !
Tune-ups depend on your budget, but the obvious ones are Forced Air intake (ditching the standard air-box). And an aftermarket exhaust, maybe uprated injectors...
The main thing is, do the mods before you get her re-mapped !!

It looks like you are the guy to hang out with.What is mods?My next porblem is ,when ever i turn on the heat,the inside of my windshield on the driver side gets cloudy(misty) what may be the reason.

[Jack Dabsy]

Mods = Modifications.
Allsorts can cause the screen to mist... Busted heater matrix, leaking hose, inside vs. outside temps, human breath and even a damp carpet !!!
