A little-known fact about factory LML/L5P Allison Transmissions is that they run at 80 PSI of line pressure. When it gets ready to shift, it spikes up to 230 PSI and then shoots back down to 80 PSI after the shift is done. This jumping in pressure of spiking and crashing puts stress on your transmission while giving you zero extra horsepower. CR2 Performance & Fabrication has the solution with its EPC Solenoid blocker. How it works is it replaces your EPC Solenoid in the valve body and works as a fooler plug in the bore which, in effect, makes your transmission run at a static pressure of 230 PSI and increases to 280 PSI off idle. Eliminating the pressure spikes and crashes, giving you much more clamping force to the clutch packs; improving horsepower, shifting quality, and longevity of your whole transmission.

Installation is simple and takes about an hour. Drain the fluid, drop the pan, remove the factory EPC Solenoid and snap it to the back of the EPC Blocker, re-install the plug like you would a factory solenoid, put the pan and fluid back and you are done!

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!

Easy
Size: CF11966&CA12166
Perfect fit. Easy to install. Good price. When changing the cabin filter the screw removal is a little easier if you notch out the plastic in front of it. Its behind the glove box and is not noticeable.
