To install the triple filters is it as simple as removing the air box, plenum etc and installing the filters direct onto the throttle body assembly. Can't find clear info online but have seen a "kit" mentioned a few times so question is, is another adaptor needed?
Also; K&N triple or Ramair?
Thanks, just planning out mod's before I start...
 
I did this with RU-2780 triple filters on a 2007 Classic. I cut the bear claw to make room. If there is a ramair available for the Touring, it should fit under the bear claw, I guess. The manifold comes out down to the air box. The filters go on the TBs. Mount the air temp sensor close to a filter between the TBs. Put a small filter on the crankcase vent. There’s not much reason to do this unless you have an aftermarket exhaust with cat delete. Then you need to make sure you can tune it.

Thanks mate. Running short pipes with cat delete (previous owner) no baffles but has a db killer.; nice sounds Getting a set of OEM pipes and plan to modify, remove cats and end baffle set. So was thinking of doing air intakes same time before a dyno tune.

@dougl I have read the triple filter set up may not add much benefit over air box under seat OEM and also read it's a massive difference. What did you find with yours?
 
A couple other notes, I did the K & N pods on my 05 Standard back in the day. I didn't get any HP gains, what I got was better airflow thru the throttle bodies. It also removed the noise insulation provided by the snorkel so I could definately hear the valves clattering in the engine bay. It was like releasing a storm of crickets when you revved the engine. Modifying the exhaust and adding a low restriction intake may cause your fuel injection to run exceptionally lean so be prepared to reflash the ECU with better fuel maps for your setup. It will also likely require you adjust the fuel mix at the last 6% of throttle to avoid an over abundance of decel pop on engine braking.

I didn’t have it dyno tuned with only the Jardine exhaust so I can’t answer that. Here are the results with both Jardines and triple filters on my 2007. I was really amazed at the torque. The tuner just used a PCIII. No change in the ignition. I imagine that with cams, the peak hp would have been higher.

Here are the dyno results on my 2005 which had the Triumph TORs with cat bypass. Not directly comparable to Jardine but no triple filters:
