Tuning Is this K&N kit okay for my 1.2?

[Tellydj]

Fair enough - I guess I'll just wait 2 years for the warranty to run out then! Meantime I'll see how using the 99RON affects the responsiveness/mpg. My Cooper S used to get better mpg on the 99RON but nowhere near good enough to help my pocket each month.

Loving my 500 though.

That sounds like tin foil hat stuff to me.
Stick in the k and n filter and change it Back to standard before your car goes in for a service or any warranty work.

The abarth ss kit comes with a bmc filter so it should be ok.

I get what you're saying, but it is there in black and white They've even got a get out clause on the BMC filter as it's still not covered even though Fiat/Abarth recommend it. Personally for the bother you could potentially have and the small performance gain, I'd just stick with standard. Just me of course

It just depends how optimistic/pessimistic and cautious/risk-taking you are.

Some people would say that the chances are that you won't have any relevant problems with the engine anyway, and that if you do the dealer won't seek to blame an air filter (or that you can swap it back before they get a chance to see it), and that if they do reject a claim you can fall back on K&N's limited warranty.

Others will say that there is always a risk, and a risk also of Fiat blaming the K&N filter, and at the same time K&N blaming something else, and you ending up the loser, or at least the person with a big load of hassle to sort out.

Then you have to factor in how important the gains that can be made are to you.

Like so much in life, there's no one right answer - all you can do is weigh up the factors and decide for yourself.
