Hi Guys
Its my first post here as i have just purchased a 2011 LW focus Titanium Diesel. Its going to be a daily so I wanted it to be a quite ride but still a bit of air intake sound and Bov would be nice. Any Idea what will go on it? Even a flat panel K&N replacement for original? Thanks RAY |

Hi, yours has a cylindrical, rather than flat panel air filter, significantly pricier than a flat panel filter. I'd be lookig at K&N or BMC personally.

Blow off valves aren't typically used on diesel engines. Blow off valves vent off excessive pressure between the compressor and the throttle body. Diesel engines do not have a throttle body.
I do know that diesel specific BOVs exist - but I don't know much about them sorry. I believe they are for more highly tuned / bigger turbo diesel engines |

I bought a K&N E-2993 $70 SCA sale. More response on the low end. Looking to get an RS Airbox next.
Our diesels DO have a throttle body, weird I know. It comes off the Mondeo since we have the same engine as them. Do a part number search on what looks like a throttle body and throttle body comes up as an available part. Yeah, weird. I think our turbos are too small, I can hear the "blow off sound" when I shift up so there's something like it happening but I doubt it's worth getting anything. Also, do the "snorkel delete" google it, easy to do. This combined with a better filter has been dyno-ed to prove that you can get some performance gains. They did a dyno test to settle the debate, haha. |

I stand corrected. First diesel I've ever heard of with a throttle body! In that case - if the throttle body controls engine RPM as in a petrol engine - then a BOV should work.

I don't know head to tail about the focus, but the ranger 2.2 has a throttle body but it only shuts when you turn the car off to stop motor vibration. Revs are still controlled by fuel delivery I beleive.

My knowledge of diesel engines is very lacking but curiosity got the better of me and I had to research it. It looks like on these DW10 engines, the throttle valves are either there as an anti-shudder measure (as above), or to create some manifold vacuum for the EGR system. They do not really have anything to do with engine RPM / load, which is still controlled via fuel injection, as per your typical diesel engine.

Did the RS intake, best bang for buck. Would probably still sound sick even with the stock filter.
Install was easy https://youtu.be/V3NODPJUx8Y |

The RRP is $149, I can get it a lot cheaper though. Yeah K&N E-2993, wait for it to go on special when SCA has their 30% off online days. No video yet of it in the car, but it sounds a bit like a Fiesta ST if you've ever been in one of those.
