What gives better performance, panel filter or induction kit?
I've an 51 plate JDM STI which is due to be mapped.
I've bought a HKS panel filter for the car but it doesn't give that nice suction noise you get from an induction kit. But my question is, what gives better performance overall when mapped, panel filter or induction kit such as K&N 57i ?? Opinions please:wonder: |
Induction Kits damage your MAF and may destroy your engine.
Panel Filters add 0.00000000000178657 of a BHP :lol1: You are not getting a re-map on a standard car are you?? |

Please, then, tell me why you 'think' you would get any improvement with a Panel Filter??? And why would it be noticeable???
And Induction Kits vibrate + coat your MAF with Oil ..... both give bad readings to the ECU resulting in a weak mixture and a melted piston or two. But, hey-ho, you think I am a fool and tool - so, you carry on :rolleyes: |

Opinions please:wonder: MAFs arent particularly brittle on New Age cars, but air filters make little difference on Imprezas below 350+bhp Simon |
I think theres a write on here showing the differences between a panel filter on induction kit on a spec c.
If i remember correctly a panel filter is better in low states of tune |
Well thats put me right off changing mine!!

If there is a chance of meltdown with an induction kit as apposed to a panel filter can you explain why please. I'm not a mechanic by any stretch of the imagination:confused: |
COME ON YOU LOT I HAVE TO BE UP EARLY!!:mad:
|
I ran a RCM induction with no probs at all. Having said that i installed a cold air feed and had the car mapped to suit.
Induction kits are only really worth it if you are going above 350+ |
Neither will give massive power increase but the stock air box is apparently good for 400bhp. If you go for a panel a search on here reveals a "green" on K&N filter are the best
Just fitted a green one to my STI PPP so feel free to read the attached https://www.scoobynet.com/general-te...el-filter.html |

After speaking to a tuner who frequents this board about induction kits/filters his words are "inductions kits are ok" i drive a newage,but i must admit i went for the Green panel filter instead which DID give me a very slight difference in power,not that you would notice it on the road, but it did show on the RR. "They" do say, however,that the standard air box (not the filter)set up is good for about 370+bhp and thats why i went for the panel filter and not the induction kit. PSlewis you tool-didn't any one tell you it is bad english to start a sentence with "And" Hope this helps. |

Cheers folks, I'm not out for mega power so i'll stick to my HKS panel filter then:thumb:
|
I have yet to hear of a new age with near standard power suffering engine failure as a result of an induction kit. Anyone prove me wrong????
That said they are a waste of money a good 'green' panel filter or such like would be better. |
as stated no big differance in panel and induction at the 350bhp mark.
can say this as i had wing induction and friend same car as me had panel filter and the was 6bhp his had 351 mine had 357 so not worth it at lower state of tune |
On their own the induction kit would not make any more power but, if mapped to suit, it will flow more air and that helps derestrict the flow into the engine. Mine made good performance with a Green Filter but makes better top end figures with the induction kit.

I asked one of the guys at the scooby garage about this last week as my car was in for MOT, he said dont bother with the induction kit as the standard filter system good enough, unless you are building a monster.
He then chucked me a panel filter (dont know what make but its got black foam pyramids on one side and a red foam panel on the other behind a black metal mesh) and told me to drop it in the car "bone dry". He said its a little better than the standard paper version, but still a better idea than a couple of hunderd quid induction on a standard car. I know sod all, so I'll put my faith in his 20+ yrs experience of working on scoobs, including the garages own rally cars. Running about with the windows down this weekend, the only thing Ive noticed is a slightly more prominent "whoosh" noise as I go through the gears, which sounds kind of pleasing. Like I said, I'm not an expert, so I took the advice of one. |

PSlewis you tool-didn't any one tell you it is bad english to start a sentence with "And" What was the Power increase?? I am seriously interested what the Rolling Road said the increase was. Was it 0.5 BHP? 5 BHP? Was the RR test done before and after fitting of the Panel Filter - same day, same RR, same weather/humidity and nothing else on the car was modified at the time? the Oil was at the same Temp.? Truth is, and everyone knows it, any power increase is in the mind - a placebo effect ......... So, leave the damned thing alone unless you want trouble by tinkering with the edges! |

Riiiiiiight, so, this Green Panel Filter gave very slight increase in Power did it?? :lol1:

A replacement panel filter which allows the engine to 'breathe' better than the standard element does equate to a small performance gain, so it's not 'in the mind'.

I'm with the saving money brigade. Over a lifetime a washable filter is bound to save cash and i'm sure more air = better efficiency if not more power.
However, although induction kits are good for noise i'm never convinced on how well they work. People end up putting heat shields and all sorts round them to keep the engine heat away, why not just leave a panal filter in its factory made box? 5t. |
The K&N site has a 'find vehicle horsepower gain' search option:
K&N Engineering, Inc. - Product Horsepower Gain It claims the induction kits (not just panel filters) can give 11/12hp increase on a 2004 wrx. It doesn't say if the filter alone makes any difference. |
Subaru don't choke the engine of air unless they need to - reduce filtration at your own risk!!
|
lol - i know this,even a 10% gain in power is unoticable on top your 250 ;)
went for the green cotton thing,waste of dosh,didint care at the time ( with the stuff to clean it with every how many months-i cant remember ) 'sooted' up fairly quick tho and could have spelt trouble if my engineer hadnt looked at it whilst plugging in mobile diagnostics machine and replacing coilpacks. Dont bother changing anything on a classic - unless your after big hp ( and for this your best off with closed deck block sti ,like i had) |
Most aftermarket filters are meant to run oiled, in which case even a drop in panel, if overoiled, can wreck your MAF as fast as an induction kit, however without oiling, some of those filters don't!

Had a panel filter at 330bhp.
Then upgraded to the larger (70mm) APS CAIK with Cold air feed. All was well when mapping. More than enough air getting in and went onto making 392/361 on an 18g. :) |
Pete-I don't have to prove anything to anybody and certainly not to a tool like you.
Now run along back under your bridge Troll. |
Harvey on here did some tests on a dyno using 4 different panel filters
In the order of best to worst for producing power... HKS Green Pannel Sponge. O/E Subaru item. K+N pannel STi panel All filters were within 2bhp of each other. Harvey pointed out that although the HKS gave the most power it was the worst for partial filtration capable of passing quite large grains of sand, now that will kill your MAF and your engine.! I cant comment on an induction kit as the last time i seen one of those it was fitted to my cossie... that was a while back..lol Rob |
