OP does not want to pay 315 USD for the spacers with out filters.

thats not the point shardul. i decide want I want to buy!
I have another problem that the stock tubes get contracted when you have Upgrade turbocharger. Brabus tested it. So my first point is to change Them Because rk kit seems long producing time.

gaspam

i wouldnt worry about stock tubes restricting hp as precision/ pureturbos just made 840whp with stock tubes

also ams intake box flexes and sucks in on the dyno as well (seen it) but still makes power

KLR CLS

UPD Kit with specter rigid hoses goes a long way. I love the look of the RK kit, but waiting on dynos and videos before making decision.

kangal63

Dyno is not the point. Heard of that Brabus recorded Videos under the Hood at driving and full throttle and there would be the contracting.
AMS has silicone tubes also a good choice I think but no plug and play solution on the market yet

kponti

Silicone will flex just like stock

I need this tube from the left side. Is this the same spectre performance tube like in the right side?

OK. You can email me

Thank you.

kangal63

Thank you for understanding. I only waiting for new results by RK. I really think the UPD Kit is the best low price version with the spectre tubes.

KLR CLS

Yes, same tubing. It has rigid wire in the corrugated sections making it impossible to collapse.

Do the rubber couplers stretch over the oval intake scoop ok? If so would I need to order two additional 3" couplers as the kit only comes with two?

Thanks Jules

KLR CLS

Each tube comes with 2 couplers. 2 tubes = 4 couplers. They fit perfectly on the oval intake scope, but you will have to put that end of the tubing in a vice to squeeze it until its oval as well. On the airbox end you will need a 3" hose clamp for each side.

Great info and thanks. Just need to find a way to get the Spectre kit sent over to the UK as they don't ship to here.

Amg63-

would combining the spectre tubes with a pair of high flow air filters like AFE pro dry be worth any gains?

kangal63

Try out the upd kit and if you dont want to spend so much money on it you can buy only the Green filters
anyone who know a bigger spectre performance hose?? 3" seems too small if you compare with stock?

Spectre intake tubes will not suck in theres no way for that to happen. As you can see from my pic above the tubes come with enough material to leave them contracted making them much larger than the stock tubes. You'll also need to trim a bit off them to fit. Been running this setup on my current 63 and my old 550 with no issues whatsoever. I also dremeled out the plastic fins in the air boxes (pliers then dremeled off) as well as the blockages in the pathway into the intake tubes located on the bumper/grille. Not sure of the gains but iat stays about 15 above ambient so must not be hurting.

TTMerc

I just measured the stock compared to spectre. Stock is MAYBE 1/8" larger if that. I dont think there's that much pressure through those hoses is there?

kponti

I have wondered if the car sucks air through the cloth tubes under WOT

Cyclone1

The OEM intake tube is also approx 3inch albeit squashed into an oval shape at the front section. Therefore no real dimensional loss / gain versus the Spectre. But would argue the Spectre due to its more rigid material aids airflow more efficiently.

KLR CLS

I did the same thing to the airboxes. The fins are there to add rigidity to the housing, but majorly block flow. I clipped them out with side cutters, and cleaned up with the die grinder. Way batter that way.

I found a bigger one in 4". What do you think of that guys??

chiromikey

It won't help if we're still restricted by the inlet/outlet.

kponti

But better (not sure how much), if it's at least not smaller than stock

TTMerc

I'm sure AMS and others that have the awesome tools to see the actual pressure in the hoses could tell us but I bet its not much unless going 100+mph. The inlet size on the air box is kind of an oval 3" wide and 2.5" tall then the snorkel piece outlet leading to the air box inlet is oval 4" wide and 2" tall. Just averaging those gives 2.875 stock crappy mesh vent is a tad over 3". You guys think going to 4 inch would lessen velocity? Are the stock tubes made from mesh to actually heat up the air for those super cold weather spots not anywhere texas?

TTMerc

Hell Yes!
I see in your Signature you have some Aero mods Splitter/diffuser did they help at all that you could tell? Is your car lowered? Bad *** setup!
