Reviews of APR parts For Business

Had a 40AE GTI for a year and recently traded in for a 20AE R. Loved the GTI, got to take it to a few track days and it held up very well to the abuse with just proper brake pads and tires

I run the full APR intake system and, most importantly, the APR Intercooler. My large intercooler keeps IATs (and therefore EGTs) down. This keeps the oil temps in the safe zone where 0W-20 still protects the bearings.

Personally, I drove at Stage 2 for a while and then went up to 3 for 93 AKI gasoline. I am happy I did. I have noticed more lag, but it is with respect to faster acceleration; I have not noticed more lag with respect to how the car drove at Stage 1 or 2. The lag is there, but as others were discussing above, I start out in race mode using the manual paddle shifters and allow the RPMs to go higher than the TCU would normally allow to build up exhaust gases in 1st gear. I then flip the vehicle into S-mode to allow the TCU to take over and the car will quickly shift through 2nd into 3rd gear, where most ppl with these cars feel the acceleration really kicks in. Also, turn off the ESC stability control; it really hampers acceleration in 1st and 2nd gear as well.... though you better keep those hands well-gripped on the steering wheel when you stop the accelerator ;-)

In 2 years/ 27k miles, I never had to add oil between oil changes. My MK7 was the same way.

The APR intercooler is very good and more than adequate for anything stock turbo. The stock intercooler is the devil, I can feel that turd heatsoaking in our current 35ish temps and anything over 40 and it feels like it's heat soaked before I even have full oil temps.

Not sure if this would matter but I did replace the coils with APR ones, from the stock ones, when I redid the valve cover seal. It has an APR stage 1 tune and and APR air intake. It has had both for the last 165,000 miles (currently has 175,000 miles).

I went APR, bought a SAI filter on ebay 25mm inlet and put that on for $3 instead of the $20 APR one. Sound is really fun. Some people online have reported some turbo inlet seal issues causing the oil that pools there to leak out. The few other owners I've asked in my local VW scene haven't come across this. I have not come across such issues but I've only had it on about 1000km in a month.

After the stage 1 APR tune almost immediately roasted my IS12's wastegate, I'm about 4 months into an APR stage 3 IS20 setup. Aside from a persistently unenjoyable power delivery, the car's been reliable so far.

Unfortunately the new plugs and coils made no difference I’m still experiencing the same startup issue and it seems like the new coils and plugs may have made it act worse.

Aftermarkets (especially APR/MST) are reported to fail often, like *very* often.
