Are these any good?

I\'m not looking to kit up my Rover 214 Si but was wandering whether fiting an induction kit is worth it?

I\'m not particularly after the increase in speed or power but would an induction kit help the engine in the longer term? Is an induction kit worth fitting as opposed to the existing air filters? I\'m really just trying to improve the reliability of my car and am willing to put in the little extras to help its performance.

There is an argument that some aftermarket filters are more efficient at filtering the air than a standard paper filter. The downside is a increase in induction \'roar\' If noise is what you are after go ahead, you will not be doing the engine any harm as it does not have a sensitive airflow meter that the oil from the cone can contaminate. Whether the filter you use is as efficient as the manufacturers original is another matter...

If you are looking for relyability you probably want a filter that is very good at filtering. Some of the aftermarket filters make make a nice noise and give a little more power but some can be pants at filtering.

My guess would be a good quality standard filter for relyability.

That tech article looks like a load of rubbish. How did they measure the power increase? I have seen one decent test of filters by the VBRA. The results did not surprise me. All filters performed worse than the standard Mann filter except a filter from ITG. I would not bother with these filters. Even IF you did get a 1-2% power gain, that difference would not be noticeable ona 214. However, if you want to make your car make a different noise, then these products will do what you want. But buy an ITG one.

Aye, but I was poainting out the filtration abilities rather than the performance. If you are after relyability you want the best filtration you can get as it will help to reduce engine ware.

As for performance I have a K&N on my nissan 200sx and when it was fitting with the filter and a performace exhuast there was a noticable diffrence in power (and noise). The combination also upped to boost by 2 or 3 psi by letting the engine breath better which would have the power too.

The filter has been on the car now for nearly 2 years and appart from neading a clean its doing well. You get good results on the 200 mainly becasue the standard setup is so restrictive.

But on a 1.4L NA engine I cant see the point realy specialy if the aim is relayability rather than performance.

If you try to increase the air flow then the airflow mass sensor needs upgrading(such as a Granetelli) so that the ECU can allow for the new increase in volume. Without doing this you are not going to see much or any improvement.K&N filters are good from a maintainance and cost point of view .The cheap (and some dear ones) hp kits are basically altering the air flow mapping.A ouple of years ago we tested many products in Germany and none did what they said and some made the car worse.

Hi,

I would suggest this: if you want to see how it will change your car's performance, run it without a filter for a short while (just a few minutes). Remove the whole air box like you would when you put the new filter on. Try and judge the performance difference objectively - don't fool yourself into thinking it's faster if it's not.

In practice, I don't think you'll find it's worth it. I used to have one on my Rover 220 Turbo (fitted by a previous owner) and when I changed back to the OE airbox and filter there was a very noticeable IMPROVEMENT (which is not what I expected!). I think this was down to the fact that the airbox draws in nice cool air from around the headlamp, but the induction kit drew in hot air from right next to the engine.

I think you can buy uprated filter elements which fit in the OE airbox. If you really want to upgrade the filter, you could do this. Personally though, I wouldn't bother.

By the way, the MEMS system doesn't need any jiggery pokery to work with a different air filter, or even without one.

Hope that helps!

I fitted a K&N 57i induction kit to my 1991 Celica (ST182), and while I can honestly say there is no increase in power, I find the noise when accelerating more satisfying!
The K&N filter is guaranteed for 1 million miles, and can be cleaned and re-used (K&N recommend cleaning it every 40,000 miles)The are very efficient at filtering dust etc.
No other modifications were necessary, as I bought a specific K&N filter for my model car, which accomodated the air flow sensor.
