BMW F Chassis M135i M235i M2 N55 Intercooler, Sports Cat Downpipe & Charge Pipe Bundle Kit | MTC Motorsport

The intercooler, sports cat and charge pipe will fit plug and play with the following vehicles with N55 engine:

• BMW M135i July 2013 onwards
• BMW M235i July 2013 onwards
• BMW M2 all models
• BMW 335i July 2013 onwards
• BMW 435i July 2013 onwards

We have engineered these intercoolers using a bar and plate core matched to our flowed cast end tanks. This is the most efficient way to keep the intake temperatures low.

We have tested our intercoolers on a few vehicles and found they have absolutely fantastic results. The IAT compared to the standard intercooler are reduced massively which means you get consistent increased performance.

The standard intercooler and the MTC intercooler both had intercooler intake temperatures of between 135-140 degrees through 5 runs on the road.

At the other side of the intercooler into the engine the standard intercooler temps were between 75-80 degrees whereas the MTC intercooler temperatures were in the high 20's over all 5 runs.

• The MTC intercooler features a massive 5" competition core with flowed cast end tanks and 4 rows extra at the front to increase the surface area
• We have added a fin to the inside of the casting on the intake side to direct some of the airflow up through the top 4 extra cores
• This intercooler weighs 11.5kg and provides near 100% more volume and 90% more surface area than the standard intercooler
• Dimensions are 520mm X 210mm X 130mm which is a huge increase on the standard intercooler. For comparison, these dimensions are the exact same as the Wagner dimensions.
• The intercooler is a direct fit and there are some great videos on YouTube to follow. However, professional installation is recommended and should take approximately 1-2 hours.

We would go as far as to say this is the best intercooler on the market for these models.

MTC Motorsport BMW M135i M235i 335i 435i Stainless Steel Downpipe with Hi-Flow 200 Cell Sports Cat

• The N55 downpipe is machined from T304 high-grade stainless steel and are tig welded in house
• Sharper throttle response due to faster spool of the turbo
• Noticeable power gains and a much more aggressive exhaust note which sounds truly amazing
• Produces lower temperatures and less exhaust backpressure due to the relief of the turbocharger. Also, the cylinder charge is increased
• There is also a substantial weight saving in comparison to the factory catalytic converter
• Mandrel-bent for better gas flow and maximum internal size to ensure ultimate performance without the loss of mid-range torque. 
• Finished in brushed stainless steel

This downpipe will fit all N55 engines from July 2013+. It will not fit the 135i pre July 2013.

We have tested this product and found increases of 10-15bhp.

Professional installation is recommended as some exhausts sit slightly different from others and can be tight although the feedback we have received from this product is that it is very easy to fit. 

If you have a later model car with OPF/PPF filters they will need coding out so you will need to find a tuning company who can do this.

Note: we cannot guarantee that this will pass an MOT test.

The MTC Motorsport N55 charge pipe features:

• Made from lightweight 6061 alloy pipe which is mandrel bent for a smooth flowing bend
• Very easy connection to the throttle body as it keeps the same CNC connector
• The pipe is 3" diameter which is matched to the size of the throttle body and down to 2.5” to meet the intercooler
• Beaded ends and mikalor clamps included so that there is no chance of hoses blowing off
• Massively increases throttle response and eliminates a lot of lag
• Meth ports welded in for those running their cars on methanol
• Hard anodised in black to improve durability.
• Direct fit
