Best closed induction system for Bug

[leonardodecappiccuno]

Hi guys, have Franken F4h-t fitted and my tuner has suggested a better intake filter system than my standard one, so that I can increase my g/s and thus more BHP.
Current g/s are 195/200, any help would be greatly obliged

Regards Lenny

Is your car chipped or Tuned? An aftermarket air cleaner system will not get you much HP gain if any unless you have a tune or are chipped and even then it will be marginal. That said I did replace my stock airbox with an AEM Dryflow Filter assembly. It looks decent and you can hear the engine a lot more than before. I think the entire set up cost me about 60 US Dollars.

She just received a custom tune (remap) 270 bhp and 300ft/lb at the flywheel, great power curve till about 5,000 rpm and then every thing dives dramatically, i.e. IAT's high, and engine start retarding the timing and so on. Have the usual mods on Bug, so the air needs a better feed to the MAF.
