DESCRIPTION

IE has worked with Mahle for several years now developing leading performing pistons offering industry-leading features. These custom spec pistons are engineered for your VW/Audi 2008+ 2.0T TSI high-performance engine build offering unmatched strength and longevity when coupled with IE connecting rods.

These pistons are engineered with compression ratios very close to the factory 2.0T TSI (EA888 Gen 1,2, &3) compression ratios. We have tested these engines with several other compression ratios, both lower and higher and found that they are very susceptible to knocking, due to the complexity and precision of the direct injection system. The compression ratio varies depending on the 2.0T TSI engine generation.

Compression ratio by engine:

VW/Audi 2.0T TSI EA888 Gen 1 & 2 (2008-2014): 9.5:1 CR

VW/Audi 2.0T TSI EA888 Gen 3 (2015+): 9.3:1 CR

OPTIONAL BORE SIZES

IE Spec Mahle Pistons are available in two bore sizes to suit your build. 82.5mm (stock bore size), when paired with a set of our rods, are ready to drop in and run in your engine without the need to remove the block. We also offer them with +.5mm overbore (83mm bore), which increases displacement to 2008cc and allows you to bore and hone the block to the exact specifications required to ensure best results. We recommend overbore pistons on most builds (unless the engine has very low miles) to ensure a perfect piston to cylinder fit and long-life operation.

REQUIRES AFTERMARKET CONNECTING RODS

These piston sets include high-quality 22mm diameter German steel wrist pins and wire locks. Strenuous testing of multiple pin sizes on this piston and engine combination has determined the 22mm pin is ideal for weight, strength, and durability. To match these pistons, a 2.0T TSI specific connecting rod with a non-tapered 22mm small-end is required. IE offers multiple industry-leading performance connecting rod options that are a direct fit and perfect match for your 2.0T TSI bottom-end build.

RACE ENGINE STRENGTH WITH OE RELIABILITY

The only way to make an aftermarket performance piston operate like an OEM piston is to design it like one. These pistons are designed with a proprietary factory-style dish on the crown, which is absolutely necessary for smooth operation with the direct injection system. If this shape of dish is not used, combustion is poor and engines do not run smoothly. In order to call these pistons the ultimate replacements for OEM, they need to fit like them. They are made with the same oil squirter notches found on factory pistons. These Pistons do not require any modifications for squirter clearance or fitment.

GRAFAL SKIRT COATING

To maintain OEM-like wear characteristics, these pistons are coated with Mahle’s Grafal skirt coating. This coating reduces friction on the skirts, keeping them quiet and from wearing over time- extending piston life. The grey appearance of these pistons is due to a phosphate coating. Providing a lubricant film in the pin bores and ring grooves, this coating is essential for initial startup and break-in of the engine to prevent micro-welding and galling. Features like these are what allow these pistons to last for thousands of miles, just like OEM units.

LONG-LIFE PISTON ALLOY

These pistons are manufactured from Mahle's proprietary 142P alloy. This unique alloy offers the low-expansion characteristics of 4032 but strength near that of 2618 alloy. The low-expansion quality allows piston-to-wall clearances to be set tight, which allow the pistons to operate like OEM, quietly and smoothly.

MAHLE PERFORMANCE PISTON RINGS

Included is a set of performance piston rings, featuring a barrel-faced top ring, ductile iron, and 3 piece oil ring. These rings are designed to eliminate unnecessary drag, which reduces friction and increases power. To maximize power output, the clearances between the rings and piston have been brought in very tightly to reduce blow by. This is achieved by hard anodizing the top ring lands, which prevents micro welding which could be caused otherwise. Beneath the top ring and second ring lands an accumulator groove is machined, which provides a cavity where blow-by gasses can collect. This reduces pressure between rings, while virtually eliminating ring flutter and keeps top rings sealed securely against the bores.

Works great!
Size: 7.5" x 8.7" x 1.4"
This is a great filter for allergies and a huge help during allergy season. It traps fine dust and pollen much better than the standard paper filters you get from the dealership, resulting in noticeably cleaner air inside the cabin. The construction feels very solid, and it fit perfectly right into the housing without any issues. If you are looking for true HEPA filtration in your vehicle, this is definitely worth the upgrade!

Saved over $60 and felt like a DIY hero!
Size: 7.5" x 8.7" x 1.4"
I bought the BOSCH 6092C HEPA Cabin Air Filter after a tire/service center quoted $76 to do the same job I did in no time. Instead, I watched a quick YouTube video, grabbed a screwdriver, and had it swapped out in under 5 minutes—no sweat, no special tools. The filter itself is high quality, fits perfectly, and noticeably improved the air quality in my car. No weird smells, and the airflow feels cleaner and stronger. Honestly, it’s one of the easiest upgrades I’ve ever done. If you’re even slightly handy (or just tired of paying for basic service), this is a no-brainer. Great product, easy install, and a satisfying win for anyone who likes saving money and doing things themselves.

Great aftermarket filter
Size: 7.5" x 8.7" x 1.4"
Performance will be TBD but after a test air does smell a bit cleaner. It Fits a 2018 Subaru Impreza just like the OEM does. Material is significantly better as well. The only thing that will cause confusion is the arrow designation many are used to. The OEM will state which way the filter is to be oriented (up), and this aftermarket version designates which way airflow goes which is usually in the direction of the blower or engine bay (down). Keep that in mind. Otherwise, it’s so easy and such a good peace of mind maintenance item everyone should do and NEVER pay the dealer.

Works ok, but not perfect. Manage expectations.
Size: 7.5" x 8.7" x 1.4"
My goal was to reduce or eliminate bad particulate odors coming in from outside while driving, as drive through areas with high particulate pollution. Sure, recirc mode exists, but then cars fill up with CO2 quickly, and high concentrations of CO2 makes you drowsy and have slow reaction times, etc. So I looked into better cabin air filters. My Subaru has an easy-to-access cabin air filter. I learned how to properly change it via online videos, because the dealership wants over $50 just to change the filter, and it only takes a few minutes! The OEM filter I took out is not that good, and only meant for larger particulates, to protect the HVAC system. It reminded me of the cheaper (but not cheapest) furnace air handler filters. Placing this new filter in and testing it, it does block more airflow, which is to be expected from a finer filter. My car's blower has 7 running speeds (plus off), and I needed to turn it up one notch higher to get about the same airflow, versus the previous filter. The filter seems to work, somewhat. If behind a diesel truck, I still smell it. Same with cigarette smoke from a car in front. It doesn't block vape vapors at all, it seems. However, maybe I was expecting too much. The infographic for this filter clearly shows the size of particulate it can handle, which I appreciate very much. Diesel exhaust is a very fine particulate, smaller than this filter can filter. I also wonder if outside air is getting around the filter in the filter housing, since it just slides in, like a furnace air handler filter. It has a good fit though, in my car at least. What I need is an even finer filter, but that would likely block a lot more airflow. There are various manufacturers of high-end cabin air filters, but I don't know if they match or exceed the quality of this one.

Good as OEM
Size: 7.5" x 8.7" x 1.4"
2024 Sub Crostrek, it fit great. I was so worried, that I need to get the OEM filter, but I went with this instead. Today as I installed the new filter, it looks as good or better than the original. I get that there's more to it than looks, but the quality of the look and feel appear to be matching that of the original, perhaps i might suggest it's even better.
