hi,just was wondering which is the best way of improving the intake on my s4, weather i should use a k@n panel replacement one, or do away with airbox an go for a induction one, i have recenty aquired a apexi induction kit whcih will fit straight on and do away with air box, but think this may not be as good as standard intake ive been told, any ideas any one?

It's best to leave the standard intake well alone, it's very efficient on the S4/S6. You could try a "performance" panel filter although there's a chance that the oil from some filters (such as the K&N) will damage the MAF wire. Plus the standard paper filter will remove far more contaminants from the air. Just change it regularly! Induction kits and open air filters will only increase the hot engine bay air being sucked into the engine and are a waste of time and money IMHO.'93 S4 Avant now back on the road complete with new shiny go faster bits. -

Just out of interest does a rs2 airbox fit?Comment

Don't know but I can't see the point. The S4 has a good cold air intake anyway.'93 S4 Avant now back on the road complete with new shiny go faster bits.Comment

Witch can allways be changed for modded one. I modified my airfilter box to have a bigger intake and have the pipe suck the air from the oilcooler passage.The S4 has a good cold air intake anyway
Subwoofer pipes rule for the airbox.
