do88 performance intercooler designed for an easy fitment in your BMW.

Significant advantages with do88 performance intercooler (OEM intercooler):
- Greater core volume: 15517 cm3 (6933 cm3), 124 % larger!
- Larger frontal cooling area , 1151 cm2 vs 658 cm2, 75 % larger!
- Air flow at 0,15bar/2,18psi pressure drop: 498 CFM (354 CFM), 41 % higher!
- Peak powergain of 13 hp! Measured on 335xi N55 with Stage 1 tune.
- Lower post intercooler air temperature at same conditions: 43°C (58°C), 15°C lower! Measured on 335xi N55 all stock except the intercooler.

This intercooler is constructed to deliver the best cooling efficiency during tough conditions. Exclusively manufactured in aluminum with continuous welds, it guarantees reliability and endurance when you really need it. The increased core volume improves cooling efficiency and lower the intake air temperature. Naturally, this being a do88 performance product, we have executed thorough, severe and continuous tests developing this product to ensure best performance. Not one compromise has been made. This intercooler is immensely optimized to the given space for an easy fitment.

The stock intercooler has quick click connections for both hoses. These connections are both restrictive for the airflow and is not ideal in terms of reliability with a high boost tune. The stock intercooler has rubber hoses and plastic J-pipe (intercooler outlet pipe).
We have redesigned the intercooler connections to conventional Ř3; (76mm) hose connections. We include reinforced silicone hoses and a 2,5; (63mm) mandrel bent aluminium J-pipe to match these connections. Our J-pipe fits together with stock charge pipe or any aftermarket charge pipe that is designed to fit together with the stock plastic J-pipe.
All these improvements result in better cooling, lower pressure drop and a much more reliable intercooler setup for high boost tunes.

The 124% increased core volume is an achievement we are proud of. It´s a remarkable difference. Perceivable, to say the least. The engine pulls better all over the revs and withstands repeated full throttle runs without building heat. The perception of an intercooler being something to upgrade only after a major engine tune is false, yet widely spread among customers and car people. During hot Swedish summer days, at repeated pulls, inspired driving or even at ordinary driving in a hotter climate area, it doesn´t take much of an effort from the engine to generate dangerously high inlet temperatures even on a standard, non-tuned, car. The cooling capacity with an OEM-intercooler is in many cases inferior which will affect the usable power outtake. The heat has to be eliminated, or else the promised output will be decreased as you start giving gas.

The stock intercooler plastic air guide will need to be trimmed (see instructions) to make it possible to install our large intercooler. This is required for most aftermarket intercoolers with a large stepped-core design such as ours. When the plastic air guide is trimmed it leaves a large gap at the top of the intercooler which lets valuable ambient air flow slip past the intercooler core. We could not accept this so we designed a plastic air guide which prevents this from happening, it is fastened on top of the intercooler core (this air guide is included in the kit).

This intercooler comes with everything necessary for an easy installation. Bolts, washers, hoses, clamps, J-pipe, air guide and installation instructions is of course included.

Do take care of your engine. Choose do88.

Highly Recommended – Saved Big and Easy Install at 83 Years Old!
Size: CF10134&CA11476
I’ve been taking my cars to my favorite garage for over 25 years, so I trust them completely. When they quoted me $150 just to install and purchase the cabin and engine air filters on my 2016 Honda Accord, I decided to try doing it myself. I bought this Cabin & Engine Air Filter set (fits Honda Accord 2.4L 2013-2017 and Acura TLX) for only about $27 delivered. What a difference in price! Installation was surprisingly straightforward. Everything fit perfectly with no issues. The only extra step was doing a simple factory reset on the control panel, which was very easy and took just a couple of minutes. At 83 years old, I’m proud to say I handled the whole job myself in my driveway. The filters seem high quality, especially with the activated carbon cabin filter. My car runs cleaner now and the air inside smells fresher. Excellent value and perfect fit. If you’re even a little handy, don’t pay the high dealer/garage prices — get this kit and do it yourself. Highly recommended! Would buy again without hesitation.

Perfect Fit & Performance for 2022 Explorer ✅
Size: CA10242&CF12772, Size: CA10242&CF12772
I recently installed this filter set on my 2022 Ford Explorer (2.3L), and I’m very impressed with the results. Both the engine and cabin filters were a perfect fit with no installation issues. Performance & Quality: Solid Build: These feel much sturdier and higher quality than the filters I removed. I bought my vehicle used, and it seems the previous owners used whatever generic parts they could find. These are a noticeable step up. Fuel Efficiency: Since the swap, my MPG has remained rock steady at 26.1 MPG while running 89 octane fuel. It’s good to know the engine is breathing efficiently. Cabin Comfort: The cabin air is noticeably fresh, and the airflow is excellent—no whistling or restricted feel through the vents. Value: Getting both filters in one set is a great deal compared to buying them individually at a local auto parts store or the dealership. I’ll definitely be looking at these again in the next 6 to 12 months for my next maintenance cycle. Bottom Line: If you’re looking for a reliable, cost-effective alternative to dealership prices that doesn't compromise on performance, this is a great choice. See Old vs New Photo

Great value and quality
Size: CF11182&CA12050
Perfect fit for turbo Civic- appears well made. I had an issue with another Honda about 4 days after I changed this and paid $28 for JUST a cabin air filter at an auto parts store. Apparently- mice like to get in there

It's a Filter!
Size: 97133L1000&28113AA100
Fit great! Just look on youtube how to put in! I'm not in a particularly dusty area, but the air cabin filter was a disaster after only a year. Will buy again!
