Hey guys I just got my 2016 bmw 340i and I'm wondering which parts preferably intake and down pipe should I get for it ? And also wanted to know if i can install a blow off valve if I get a charge pipe for it ?

Drop in filter is going to give you as much performance as any intake would, only benefit of a different intake is going to be if you want more noise. Paper filter is also sufficient but custom tuners (Cary Jordan as an example) has recommended upgrading the panel filter.

I opted for a catted downpipe as they have been rated to give 97% of the performance a catless downpipe would, without the added smell of catless.

B58 Engines and our turbo's don't have Blow Off Valves, it's handled by an electronic wastegate.

B58's also don't have the charge pipe issues N55's do. Charge Pipes have been rated past 500whp so you're good there.

I'd recommend the following

AFE Dry Flow Drop-In Filter
CG Precision DS-1 Downpipe

Thanks bud really appreciate the information

hey im running a vrsf catless down and dinan mid pipe plus an aftermarket air filter on stage 2 93 octane with bm3. love it car runs smooth. hope this helps.

I’m running a Remus cat back ,AP intake just ordered a Wagner 200 cell down pipe and BM3
Will report after bootmod3 is installed

I'm curious. Are you certain that the B58 engine does not have any type of blow off valve (also called a diverter valve)? The most recent version of the N55 engine, starting in July 2013, has both an Electronic Waste Gate and a Diverter Valve.

Trying to find the full technical document for you but here’s the excerpt from that the B58 engine spec doc.

A blow-off valve is not used in current models. Pressure peaks, caused by sudden load shedding due to the inertia of the turbine of the exhaust turbocharger, can be avoided by careful tuning of the Digital Motor Electronics software. With foresighted charging pressure control, pressure peaks can be predicted and reduced by quick adjustment of the electrically-adjustable wastegate valve. Assisted by a delayed load control of the Valvetronic (in the minimum lift direction) or the throttle valve (in the closed direction), the remaining charge air which is produced can be routed to the exhaust emission system via the engine. This form of control thus prevents the exhaust turbocharger shaft from being exposed to excessive torsional stress due to high pressure peaks.

BM3 + Intake/Filter + Downpipe

Performance wise intake or filter will give you same power but an actual intake sounds a lot better

If you're in the tristate hit up bm3tuning bm3 and cts downpipe and intake you're all set sound power and quality

As much as it was said the B58 has no diverter valve, something is dumping a "whistle sound" on hard gear changes on my 2016 at lower gears. There is a 4-way stop by work that once you clear the intersection with the windows down, sound bounces off the stop sign with a clear "pressure dump sound" that I'd say was a diverter valve. It is 100% outside the cabin, and VERY noticeable.

Yes I did well not custom but they sold me my bm3 license and walked me thru using it...hit up, bm3tuning or @tristate********* tell them Aris sent you they'll take care of you I ordered my cts downpipe from them which is coming in this week and my plugs as I'm at 17k and need to gap them for stage 2 so rather have them ready

Thank you for the shoutout!
We take care of all our Tristate friends

Will be reaching out after I get the Wagner down pipe put on
Just did the mppk map not even stage 1 but it’s very easy and fast

for stage 2 need to gap the sparks plug?

Depending on the car for stage 2 e30 you experience better power delivery with gapped plugs

If just for Ron98 dont need to gap?

I have the same questions as well: for RON98 (or the US 93) do we still need to gap plugs?

[OzBMR]

I run an MHD Stage 2 tune with stock DP, stock intake and filter panel, stock Champion plugs gapped as they came from the factory, E30. Data logs and power is perfect. Good for 11.5@121mph

Champion OE245? i see in description "electrode gap" 0.8mm like on OEM Bosch

Yes, that was OEM when my car was built by BMW and 0.8mm (0.0314961")

I have some NGK 94201 SILZKGR8B8S that I'll replace the Champion plugs with when I need to.

I'm at 37,000 km (23,000 miles) and unless any issues will change at 50,000 km and leave as gapped by NGK at 0.75mm.

I've pulled the Champion plugs recently to see how they're going and they're looking good.

+1 on CTS Turbo Downpipes
I believe elg0rd0yadigg is working on a multiple car discount deal (Intakes/DP and Spark Plug) from the local Bootmod3 Dealer in our state.
