the air filters do not work - there a waste of money - same on the 172 as well. they may make your car sound better but the loose performance. FACT. Renault spent millions developin the v6 so im sure some back street tunin company that have just wipped somethin up in there w/shop wont be able to improve performance - besides the ecu would correct any noticable air flow increases via the maf sensor and run the mixture weak or high to compensate for the increase. how do i know - ive tried em all.
Renault spend millions developin every car they make mate, however everythin can be improved upon, however small the improvement may be
yes most induction kits are crap but only because the owners dont supply them with proper cold air feeds and/or some kind of heatshield.....
aftermarket filters do flow better especially as they get dirty, in comparison to a paper filter
V6 Clio
CB1A,
Have you tried the Viper Race filter as on K-Tecs website? The picture there is of the first one being fitted into my car (FOC). They told me their standard Viper is only rated to about 230-250bhp so wont do much for the V6. The Race or EVO as it is also known is rated to over 500bhp but the other advantage is it takes out the right-angled bend out of the original airbox and provides a staightline feed, you should be able to see that from the pic I think. My car has not been tested for power but I believe there was a noticeable improvement in mid-range power. I can bearly hear it roar compared to the original as my replacement exhaust is so loud so I dont believe it is psycological and I didnt have to pay for it as my car was the guinea pig. Im not trying to defend a £250 outlay therefore. If you have tried this fair enough, if not I think it might be worth a go.
I did pay for a superchip though and dont think it made any difference that I could tell!!!! (except better mpg when cruising)
this is getting amusing - any increase in flow whilst filtered correctly and mapped correctly will improve things - the standard ecu is mapped for crap fuel in the worst european country (94 ron) - run optimax and increase airflow and things will be a little better (few bhp and better mid range marginally).
The superchip advances the ignition a few degrees and pretty much nothing else - I too had one and noticed little difference other than pinking on low ron fuel!!
The best increase will be from remapping a new ecu for the fuel you can get here with the air flow as cold and unrestricted as possible (whilst filtered)
renault do spend millions but they also build in a fat safety margin for poor fule and high air temperatures around europe in particular and then detune everything to contain warranty costs.
All of the above will of course kill your warranty!!!
all for a 0%-3% increase, wahoo!
Back in the good old days whackin on some k&n to your carbed car was the right thing to do, now days as CB1A rightly says manufactures do little wrong when it comes to filters, its not worth the bother of £200+ for a cone filter (only one which will give you the slightest of increases), a re-map, rolling road session, warranty problems, insurance problems, worse economy...and then once the f**king thing isnt new anymore you lose the gain!
