Airtec Motorsport Stage 4 intercooler upgrade voor de Ford Focus ST225 Mk2 2.5 Turbo, ontwikkeld voor zwaar gemodificeerde voertuigen met vermogensniveaus van 400+ pk. Deze setup is bedoeld voor eigenaren die het maximale uit hun Focus ST willen halen tijdens sportief straatgebruik en track use.

Voor de Stage 4 kit heeft Airtec de populaire Focus RS intercooler aangepast zodat deze perfect past achter de bumper van de Focus ST225. Daarnaast is het bewezen 2.5 inch big boost pipe systeem aangepast voor gebruik met de Focus ST turbo, waardoor de complete luchtstroom tussen turbo, intercooler en motor optimaal wordt benut.

De intercooler maakt gebruik van een 60 mm high-flow core die ongeveer twee keer zo hoog is als de originele intercooler en bijna 100 mm langer. Hierdoor ontstaat een enorme capaciteitsvergroting en een indrukwekkende 127% toename van het frontale oppervlak ten opzichte van standaard.

De combinatie van de smooth-flow gegoten end tanks en de geïntegreerde Air Ram Scoop zorgt ervoor dat rijwind maximaal door de intercooler wordt geleid, wat resulteert in aanzienlijk lagere inlaattemperaturen tijdens langdurige belasting.

De meegeleverde 2.5 inch boost pipe upgrade vervangt het originele 2 inch leidingwerk. Dankzij de grotere diameter wordt de luchtstroom minder beperkt, wat resulteert in betere respons en meer vermogen. Tijdens rollenbanktests leverde alleen de boost pipe upgrade al een winst op van 11,8 pk en 12 nm koppel.
Wil je de originele symposer behouden? Maak dan de keuze voor de cold side boost pipe met symposer outlet.

De intercooler is leverbaar in Pro-Series Black of Natural Silver. De boost pipes worden uitsluitend geleverd in Pro-Series Black.

Belangrijk voor pre-facelift modellen: De pre-facelift Focus ST225 beschikt over een andere radiateurconstructie dan de facelift ST225 en Focus RS modellen. Hierdoor kan de linker (cold side) 2.5 inch siliconen slang zeer dicht langs de radiateurdrager lopen na montage van deze Stage 3 kit.
Om voldoende ruimte te creëren adviseert Airtec om de bout van de radiateurdrager te verwijderen, de drager iets naar rechts te verplaatsen en vervolgens een nieuw bevestigingsgat te boren voordat de bout opnieuw wordt gemonteerd. Dit is een eenvoudige aanpassing die slechts enkele minuten extra werk kost, maar noodzakelijk is om voldoende vrije ruimte te creëren voor de grotere 2.5 inch cold side slang.
Mocht de beschikbare ruimte daarna nog steeds onvoldoende zijn naar wens, dan adviseert Airtec om over te stappen op een Focus RS radiateur, die meer ruimte biedt rondom het leidingwerk.

Veelgestelde vragen

Wat is het verschil tussen de Stage 3 en Stage 4 intercooler?
De Stage 4 is ontwikkeld voor zwaardere vermogensniveaus van 400+ pk en maakt gebruik van aangepaste 2.5 inch boost pipes die specifiek zijn afgestemd op de Focus ST turbo.

Voor welk vermogensniveau is deze kit geschikt?
Deze intercoolerset is ontworpen voor zwaar getunede Focus ST225-modellen met vermogensniveaus boven de 400 pk.

Leveren de 2.5 inch boost pipes daadwerkelijk extra vermogen op?
Ja, tijdens rollenbanktests werd een winst van 11,8 pk en 12 nm koppel gemeten door uitsluitend de grotere boost pipes te monteren.

Past deze kit op pre-facelift modellen?
Ja, maar Airtec adviseert een kleine aanpassing aan de radiateurdrager om voldoende ruimte te creëren voor de grotere 2.5 inch siliconen slang.

Buy it! Lifesaver!
Size: 16oz
Yes, buy it when you don't have a spare tire because you will need it! I live in Florida and flat tires are just part of living here! Saved my life twice already and is absolutely self explaining! Cheaper then a spare tire, lighter than one too! Just throw it in your trunk and best case you will never need it but just in case!

Difficult to use and eventually hose end broke
Size: 24oz, Size: 24oz
I purchased this can of Fix-A-Flat to fix, what I believe, is a rim leak on my truck tire which needs to be filled once every week or so. When I attempted to use the product I let some air out of the tire (down to 25 psi) so it would be easier to dispense the contents. The instructions on the can say to have the valve on the tire at the 6 o'clock...which I did as well. When I attempted to make the connection using the swivel connector on the can's hose it was difficult. The hose on the can is very short and stiff and because it came coiled in the can's lid, did not want to straighten out making connecting it to the tire a very awkward process. It was hard to screw the hose end on the valve without it binding so it felt like it was cross-threading. I have machined aluminum valve caps and they go one very easily so I know the threads on the tire's valve stem are clean. I finally did get it on and when I attempted to dispense the contents it filled the hose but that was about it. I could not see any contents flowing thru the hose at all. I assumed it was not on far enough so I took it off to try again and the contents sprayed everywhere showing it was indeed under pressure....just not going into the tire. After multiple tries the hose end eventually just broke off and stayed on the tire's valve stem. I was able to get it off, but at this point the can is useless to me. Obviously I cannot and will not recommend this product. I have used this product before and had success, but that was when the hose was longer and wired to the side of the can making it much easier to use, versus how they are shipped now. I would recommend going with another product or possible going to a box store (which is what I plan to do) to find one that does not have this design. At the very least, if you do choose to disregard this review, I would try it with the tire's valve stem at the 3 or 9 o'clock position which might make it easier to thread the hose end on to the valve stem,. Also, if you choose to go this route you might just be throwing your money away. I attempted to get a refund from Amazon and was directed to the manufacture's web site. From there you are directed to use the 800 number of leave a general message that is in no way connected to your Amazon purchase. Past experience tells me it will not be an easy process so it looks like I am out the $12.

This is a necessity for anyone that tries a car!!
Size: 20oz 6pk
I haven’t used this yet, but I bought a case to give to my family members. My friend who came outside to a flat tire. It was a Sunday in Utah so there was really no one that could fix it. Walmart told her to get this product. She had to drive home immediately following using this product (300 miles) It has been over two months now and my niece is still driving on that tire. It was a brand new tire that was costly so she decided to just wait and see how long this product will work. Great gift for anyone in the family that drives. This does not work on a blown tire. If you wake up in the morning and your tire is flat, or you get out of class and your tire is flat, just use this product and no calls need to be made.

👌 Kaboom! 🌹 Air fills the room! 💥 Inside your tyres, that is ✨💖
Color: Orange, Number of Items: 1
Right out of the box this little wonder inflated my motorcycle tires to the decimal. I set it to .5 over on the digital pressure gauge so the pulling out doesn’t lower the PSI. This machine worked easily, flawlessly, and if you’re on the fence, I’d say pull the trigger. The hoses on mine screwed together making it just about the right length. Dunno how long it lasts but - wow - not much bigger than an old transistor radio & was controlled intuitively. Easy port on bicycle, cycle, auto. It’s a wow & I’m hard to please.
