K&n filters on twin sus hs6
 

Is anyone running these filters on twin sus, I’m thinking of having my carbs rebuilt with these but would like some vibes if it’s a good idea. The carb man certainly think it’s a no brainer compared to the pancake filter box. Apart from the box being unsightly (in my opinion). Im all up for a little more poke.

Box may be unsightly but it flows better, filters better and is quieter, especially if you have the correct nozzle on it. K&N very expensive and need to be oiled. The big blue Volvo ones are not as expensive and filter more consistently.

Not the best pictures, but on my MGA, I'm running the set up on the right with H6 carbs.

Velocity stacks for the HS6 carbs:
K & N Air Filter #RU-4410


I bought the setup from namvet6970 here. https://www.ebay.com/itm/2-Alum-Velo...-/202038206635


Air filters slide on and off with a turn of one screw.

I'm sure it would work just fine on the Volvo.

I've got a K & N inside the pancake filter box. Fits about perfectly.

I can't remember the part number but I seem to remember K&N had/have an excellent facility where you can search by dimensions.

I was looking to get rid of the pancake box all together. I’ve heard the K&n can be noisy but are said to perform better allowing greater airflow.

Use the box and add an extension tube tube to pick up clean cold air from just behind the grill. That's what I have done on the 144. Not very elegant at the moment. looking for a smooth bore flex tube with the correct dimension

Twin K&N's probably perform better than a pair of the Volvo blue filters, and I'm sure the pancake K&N performs better than the pancake Volvo filter. There is a marked increase in induction noise if you don't use the filter box however, and you do get the benefit of using the induction hose through the front panel for cold air. My car also has the Volvo valve which allows warm exhaust air to help on cold mornings. For me, at least, that set up on a daily driver is the best compromise. I had a pair of blue Volvo filters on, I liked the induction noise for about a day, then it became annoying. I could not notice any difference in power between the twin filters and the box with a K and N in.

Here's a link to the one I have.

I've got the twin K&Ns on my SUs and I actually like the sound... nice complement to the sport exhaust.:cool:

Thanks all, varied feedback but thats us volvo drivers all over I guess. Rob and Emma think there is no better air filter than the existing box, mr carb rebuilder says you cannot beat the K&n set up! I think I’ll get it set up, run about for a bit and see how it works for me. If it’s no good you might see a pair of refurbed sus with K&n set up for sale soon!

Thanks all

The air box with a K&N panel filter is the best bet.
