K&N 57S or J1automotive air box intake ?

[Jadejaws84]

Which one should i go for ?

 

 

(Not interested in a replacement element)

Don't bother with either. Your stock CAI will outperform both of them.

What do you want from it ? .....More intake noise because thats all you will get  no performance benefits at all.

I am going to fit a Volkswagen racing panel just because it will turn out cheaper in the long run due to the high mileage I do 

I think  there was talk you need to be running Stage 2 + to get any benefit

Any tuner info on this ?

 

What I'm after is better throttle response and,a little extra power.

 

I will be having a map done on it at some point.

You wont get it fitting a different airbox or filter 

Also look at some of The Yeti Projects for some of the mods they have done to them..

Ask any tuner for these engines

 

The one below seem quite populer on this forum

The engines dont have any air restriction problems so fitting a different one doesnt work till your going way above Stage 2

I'm not sure what performance gains you get on diesel cars with a different air box. I use K&N (filter not box) on my petrol 3.6 and I'm happy. I've posted elsewhere on this (do a search...).

As I understand it on diesel cars from reading the forums, full K&N plus chip/remap plus decent exhaust will do the job.

Have fun!

K&N filters, and oiled filters in general, tend to shorten the life of MAF sensors by coating them with an oil film which burns them out. They're also much more porous than the stock filter so larger particles can get through into the engine and cause damage.

 

Some aftermarket air intakes place the intake inside the engine bay where it's drawing in very warm air. The stock air intake has the intake at the top of the radiator grille, just below the edge of the bonnet. This is about the best location for getting the coldest air possible into the engine.

 

If you really think you need more airflow into the engine, you should be looking at getting a paper type filter with a larger filter area and replacing the air intake components with larger diameter parts. This won't really be an issue unless you're aiming for huge power increases and even then I doubt it'd make much of an improvement.

 

The overwhelming majority of the time, aftermarket filters/intakes are an expensive placebo - a triumph of marketing over engineering.

A remap alone will give you the desired result. I just had my Greenline remapped by Superchips and am now running 148bhp, the car has been totally transformed.

I've run K&N oiled filters on all my cars (turbo and NA) with no problems (e.g. 125K miles on a modified VR6 Golf, 78K on A4 turbo etc). Now running a K&N panel filter for the last 32K miles and the MAF is pristine as is the air in-take duct. I've tried both CAI and a short ram intake - complete waste of money. No extra power and lots of induction roar! (Ram actually lost some power).

 

Some MAF sensors suffer from silicone contamination, which originates from the sensor housing itself, due to degradation over time of the MAF unit. This leads to false MAF readings and so the ECU runs the engine lean -  which is really bad news. K&N have done extensive testing with over-oiled filters and have not been able to get oil particles to foul the MAF.

 

Best mod for your £ is a remap. Diesels respond really well to an ECU re-tune without the need for any other alterations or mods. You'll get better average MPG too (unless you can't resist flooring it all the time!).

If you really want one then go for the VWR Intake, great induction sound and sets you up for future mods (turbo, intercooler etc)

I love it on the Yeti project

[Jadejaws84]

I ended up going for the K&N and there's no difference in sound but,throttle response is slightly better.I've only done 20 miles.

The oil spill affecting maf sensors is a bit of a wives tale. Yes, if you stupidly oil a pre-resignsted filter you may cause issues but if instructions are followed they are no worse than standard filters - and do not affect warranties etc.

Just leave the airfilter and assembly alone , get it remapped
