Ultimate Induction

Welcome to what we hope will be the first of many product reviews appearing in FTO News. I would just like to take this opportunity to thank all those suppliers, listed at the end of this article, for their generosity, without their kind donations this and other reviews would not be possible. 

Right, enough buttering up the suppliers, down to business....

Engines need three things to make them work, fuel, air and a spark. To gain more power the engine needs more fuel to flow into each cylinder. The FTO is fortunate in that the ECU constantly calculates the air/fuel ratio by monitoring the exhaust gasses using a lambda/oxygen sensor. The ECU then adjusts the fuel input accordingly. So to get more fuel all you have to do is introduce more air into the equation and the ECU will adapt.

This is why an air filter is one of the first modification most people do to their FTO in the vain hope of a few extra bhp, but  just how much extra can we expect for our £`s. We decided to review some of the most popular filters available for the FTO.

K&N		Replacement Panel Filters	Momo
	Replacement panel filters, I've always been a skeptic about these. Could they really increase bhp by just dropping one of these in the standard air box ? Well the answer is yes, both the K&N and Momo performed well increasing the output by an average of 4 bhp. So for around £40 these are a great alternative to the standard paper filters. They are reusable and last on average for approx 100,000 miles.

Drilled box with Momo Filter

This was the shock of the day. The standard Momo filter gave 4bhp when we drilled holes in the air box we got an average of 5.5bhp increase, with one run actually giving us 7bhp. This would be the cheapest option for people on a budget. A Momo or K&N replacement  filter will save you money in the long term and drilling holes costs you nothing.

Before we review the bolt on filters, it has to be said that if its a nice throaty induction roar that your looking for any one of these filters will suffice. They all sound superb, when the MIVEC kicks in.

RACTIVE : Kits & Bits 01472 753711	K&N 57i
This is one of the better looking filters, The actual Filter comes in a number of colors including a carbon fiber look-a-like. Unfortunately on the tests this actually lost bhp over the standard filter. Possibly because the air intake can not draw enough air into the MIVEC engine. Replacing the filter with one of the others mentioned here should give better results while still keeping the nice stainless looks. A number of people have put these filters onto a GS`s and say it boosted performance.	K&N Probably "THE" best known producer of after market filters in Britian. That aside, the K&N put up a good fight on the Rollers giving a 7bhp increase. It was a slightly unfair test for this filter as it comes complete with an intricate cold air ducting system to draw cold air form the front of the car. Under road tests it would probably have done better against its rivals.

ITG : Camskill  01946 694794	BLITZ : Racelogic  01280 823803
A triple-layer polyester foam filter supported by a stainless steel mesh. Not the best looking filter we tested, it would look more at home in a bath than an engine bay. It was a breeze to fit and out performed our expectations giving a massive 8.5 bhp increase. Its cheap price tag of just £66 makes this our  Best Buy Filter !	The BLITZ Filter is made from incredibly fine T304 stainless steel. It was by far the best looking filter we tested and very easy to fit. We all expected this to come out tops on the bhp tests, sadly it didn't. However it did perform well giving an 8bhp increase. Unfortunately its hefty price tag of £182.13 drops it to third overall.

Green	APEXi : Ultimate Performance Autosupply 0115 9127010
Well errrr...Its Green. That's what I can say its green ! Hmm ...that's not much of a review ... OK I need to add a little more. This was the cheapest air filter we tested, even cheaper that the replacement panel filters and it just managed to outperformed them. Giving an average of 4.5bhp increase. To be honest unless you've got a green car, get a replacement panel filter. They look better because you cant see them. I apologies to the one person out there who has replayed his FTO this color (someone probably will have !)	This is one sweet looking air filter. Both on and off the car. With its price tag of £176.25 we were expecting great things, similar results to the BLITZ and HKS. Unfortunately it did not perform. It only gave an average of 4.5 bhp increase. Not enough blow for the dough!

HKS : Ralliart UK  01384 216100

HKS, Super Power Flow, nicknamed the "green hairnet" by some. Maybe not after today.  It has been "engineered to dramatically reduce inlet restrictions" and boy does it ! On one of the runs this filter gave a whopping 199 bhp Thats 9-10 more than standard. Which makes it our 

Best Bhp Filter 

Its easy to fit and clean and the Green foam can be replace with a number of different colors, which has to help in the looks category. This makes the HKS Super Power Flow our all round

 Winner

[난 누굴까??]

성능이 가장 좋은건 HKS구 가격대 성능비는 ITG제품이 제일 좋은 건가요 ??? 그렇게 보이는데 아닌가 ㅋㅋㅋ

[Soong]

RACTIVE<- 이건 쓰레기군

[Luxury]

내차 흡기가 HKS인데 왜 내차는 느릴까요?

[현택]

나도 버섯돌이 원츄!

[1100]

해석버전없나요 ^^;;

[無聊한人生]

ITG 구해봐야겠따 아니 근데 HKS 가 ITG 보다 3배가 비싼데, 우리나라에서는 왜 ITG 가 더 비싸지 ? 옘병 !

[데스윈드]

굉장히 좋은 표현이군...... 1마력당 돈이라? ㅋ 그리고 ITG는 2만키로마다 걍 클리너 가져다가 닦기만 하면 되지만 HKS는 5천키로마다 교체하는게 원칙이라 카더군요. 버섯돌이 교체용이 3만 5천원 하니. 유지비면에서는 ITG가 더 좋을듯.
