i have a renault clio 1.2 1995 (no modifications yet!)
so if i install these two:

[b]K&N E-9136 (Replacement Air Filter)
K&N 57-0052 (57i Intake Kit)[/b]

what would be the benefits and dowsides? (eg. how much hp would i gain? what would the sound be like? how much will the fuel consumption increase?)

thanks for all the insights!

I would think the only noticeable difference will be that your wallet will be a little lighter.

why? is that engine too weak for tuning or? and what about the sound or mpg?
and it really isnt a big investment - less than 100GBP

No, it's because pissing about with "intake kits" on a standard modern engine makes no noticeable difference.

It might make it noisier so you think it's faster, but that's about it.

modern? it's an engine designed before 16 y, at least!
this mine in particular has just turned 10

It depends wheteher the OEM air filter is restricting the air flow or not. You'd probably get at most 5bhp gain if it was. It's not uncommon for aftermarket air filters to actually reduce power.

Go for the panel filter, you will get a couple more hp.. but the induction noise will be a bit better, mpg will prob not get better or worse.

The full intake kits are not really worth it for lower powered cars.. and they don't really work without a cold air feed.

im not talkin just about power...
actually the main thing i want to know is what kinds of modifications can i do to my car so it has better mpg?
i heard that a good aftermarket filters can improve mpg by 5-20%, prolong engine life, also give you a bit nicer sound

Not been nasty but where did you read that, the manufacturers website? K&N filters are meant to be "better" due to allowing more airflow for similar levels of filtration but the main feature of them is the ability to wash and re-oil them. Older cars see a dramatic improvement (due to the actual design on the airboxes/filters rather than the filter itself) but in reality if they were that good, why aren't manufacturers supplying them as standard?

To improve MPG? Use a lighter right foot and spend the £100 you'd pay on the new airfilter (and subsquent increase in insurance payments when you tell them you have a "power mod" on fuel. Far better idea IMO. If however you are really serious about improving MPG by modifing the car, then don't look to the engine, but look at what the engine is moving.

Take all excess weight out of the car, make anything that sticks out and increases the friction of the vehicle off (i.e. wing mirrors, aerials, scoops, spoilers...), get some new tyres with the smallest possible rolling resistance and make sure they are the required gearing (i.e. don't make them too large or too small), remove anything that takes power from the engine (i.e. stereo, electric windows/sunroof)...

well... i drive it in the city and it's around 10 liters per 100km... (25 us mpg / 30 uk mpg) www.teaching-english-in-japan.net/conversion/miles_per_gallon

to docevi1:
i didnt read it... some people told me... well of course, you can read some ""feedback"" here: http://knfilters.com/feedback.htm

but it looks pretty much logical to me that if you take a air filter which design dates about 15y ago, and replace it with a modern and more expensive one, some improvements are bound to happen.

also thanks for all the things you mentioned, i'll take my car to a diet now

anybody else has any suggestions? thanks!
and what about engine sound?

I've heard that fitting a main sail can improve fuel economy! If you're really serious you could add a jib and spinnaker.

I wonder how the plod would feel if people jibed up the M1!

If seriously, all you're interested in is mpg, then trade it in for a small diesel.

EVEN if it did give you a couple of BHP do you think you would even notice it? As others have said, your'e wasting your money.

It just makes it sound different and it would appear that many people just like fitting stuff like that so their signature on a forum looks more impressive, like some sort of roll-call of crap they bought of ebay recently.

ive tought about it throughly and i plan to install just this k&n air replacement filter i mentioned above, for various reasons...

just another quick question: what would i gain if i install a new exhaust (some bigger-sporty one)? any other ways i could increase speed and acceleration?

essentially, im interested in all possible car tuning except for it's looks (body) and audio systems, so if anyone has a nice suggestion please do tell!

If you are looking to increase speed and accelleration, then why a 1.2? the Volvo 1.7 turbo engine is an accepted upgrade for renault 5's lagunas and clios...We have had a few people come and hassle us on the 480 forum

The most economical way would be to junk the Clito and get a faster car to start with
