Not sure.. the former owner installed it. It's not from a subaru Sti.. just an aftermarket brand of coil pack.

Used oem coilpacks used to be kinda hard to come by. Now they are 15 a piece shipped.

5280 Nogaro S4

And an STi one works and fits.. Cause i have a hard time believeing that that is just a random company that sold aftermarket not subaru part that is pink with the same emblem.. I think its a paint job or sticker lol..

Of coarse it was an O2 or an EGT sensor, I don't remember anymore. I almost had to say the "It adds 20 Hps" too.

STI = Spark Transfer International. They're a US manufacturer of ignition products.

It's shown on page 33 of this product catalog:

V6 2.7 LTR. (APB) Turbo

"<SMALL>Karlyn Industries is recognized as a leading manufacturer of Ignition Cable Sets for the automotive aftermarket and as an Original Equipment Supplier. The company manufactures and packages wire sets under different labels, including their own brand-name, "S.T.I." (Spark Transfer International). Karlyn's Engineering/Research Department is headed by Mr. Karl Bierdumpfel, a graduate engineer from Stevens Institute of Technology, in Hoboken, N.J. Karl listened to the market which begged for a high-quality ignition cable set line that was also cost effective. While other wire set assemblers were becoming totally automated at the expense of high quality detail, Karlyn Industries increased the hand work portion of its operation to allow for the intricacies that are desired on certain ignition cable sets. This resulted in a mass appeal of Karlyn/STI ignition wire sets which is why they are the fastest growing wire set line today. In 2004, Mr. Karl Bierdumpfel assumed the role as President of Karlyn Industries Inc.</SMALL>"

5280 Nogaro S4

Interesting to know.. funy that the emblem looks just like the STi one tho and is in hot pink.. I mean not every one goes YES!! I want to do it in hot pink haha


So can anyone explain more about the GT28 turbo kit or setup?

Autospeed came out with their GT kit quite a few years ago. What is there to know? They fabbed custom manifolds and downpipes to fit the larger turbos. Bigger turbos can maintain more boost at higher air flow rates.

I'm going with ASP but there are tons of options for B5 S4's these days.

5280 Nogaro S4

I was trying to search for the kits but didnt have much luck.. I also read that you have to do internal work and stuff to be able to support them..

What all is required?

5280 Nogaro S4

Ok so if I bought an Autospeed kit.. What else would I need or do You recommend. I have a bone stock S4 right now.

Some one correct me if I'm wrong. New rods to support the extra torque. Some people go with upgraded pistons, although not everyone. The pistons are a nice complex issue changing the compression ratio and or reducing mass. Upgraded valves and valve springs. I assume that every one who does this puts in new lifters too. Lots of people are also going with the 2.8 heads. The upgraded valves and valvesprings to raise the redline allowing you to take full advantage of the larger exhaust turbines, and better highflow potentials of the GTs.
