The engine air filter needs replacing on the 500, so I'm thinking that I might as well put in something better than the OEM Fiat one. I'm not looking to go all out and put on an induction kit; just a different panel filter.


Does anyone have any recommendations on which panel filter to buy? There's quite a few manufacturers doing them?


The engine in the 500 is the 1.4 16v non-turbo (from the Panda 100hp).


Thanks!

There is no MAF on the 500.

• BMC = 293/04 or FB293/04 (£40-45)
• K&N = 33-2842 (£38)
• ITG = HMP-576 (£58-76)

Had a look online, for the Fiat 500 1.4 16v there these panel filters available:

• BMC = 293/04 or FB293/04 (£40-45)
• K&N = 33-2842 (£38)
• ITG = HMP-576 (£58-76)

Green don't do any filters for the Fiat 500.

Fiat always use BMC on esseesse upgrades.

Construction is just like K&N

There is a slight sound difference but not very noticable. The 'air box' kills most of the induction noise.

Is the sound difference between the bmc and k&n or any uprated filter vs stock? Just im planning on getting the bmc filter for the 0.9 when it arrives

Fitted the BMC Panel Filter. Don't think it makes any difference... well unless you use the stickers that come with it, as they've got to be worth 10hp each .


Have to say that I'm not a fan of the OEM airbox design, and if it weren't for the fact they cost £200 I'd be tempted by the BMC CDA or GSR Induction Kit.

Ha ha, maybe a slight improvement you can't detect? My TA dyno'd @ 90bhp and 111ft lbs - more than quoted which could be to do with better 'breathing'

You really had the engine pulled and dyno'd on a proper engine dyno? If not then that figure is 'adjusted' and even if the adjustment is correct, it's probably more indicative of a more efficient than average drive train/ tyres than a panel filter gain. Rolling road dynos are most often used on modified performance cars with big sticky tyres, if you swap on a set of eco tyres the dyno will show some pretty big power gains, typically, the adjustment figure will be set for the big tyres.

The official figures are supposed to represent an 'average' car, there can still be variances plus or minus. Finally, if the car was tested below 25*C ambient you should expect a gain. This can be factored in, but might not always be.

At what mileage did you run the test at? Regardless of all the above, it's an interesting data point.
