ITG Air Filters New Drop-in ProFilter(s) For BMW M Cars
For over three decades now, ITG Air Filters has been at the forefront of racing air filter technology - plugging away at both competition and road cars with some truly epic results. This continued, accomplished evolution alongside motorsport and racing success always trickles down to the street eventually, so whether road or racetrack be the destination, the same principles of maximum power and faultless filtration always apply. With a collective of power-hungry megalomaniacs based at Coventry HQ, these handmade-in-the-UK filters continue to offer stunning results thanks to the high-tech TriFoam blend for fantastic efficiency gains over the OEM, off-the-peg, budget filters. You see, to unleash the true performance potential of BMW M cars involves turning to a true, motorsport-approved stalwart of filtration – yep, that’s right, ITG.
Lacking in power isn’t generally something the BMW M-Sport cars are well known for, but with the latest batch of BMW F30 / F32 M3 and M4 and also the F10 / F12 M5 and M6 there’s still room for a little improvement, even if it’s merely a pair of drop-in filter upgrades to really make the most of the turbocharged straight six and V8 respectively. As perfectly balanced, fast, effortlessly rapid road cars these typically enthusiast-owned vehicles are primed for further modification to extract even more excitement from this ferocious quartet of Bavarian bruisers.
Hence the development of WB-429, a brace of drop-in ProFilters that promise to deliver perfectly filtered air from within the factory airbox to enhance throttle response and driveability throughout the entire rev range. Suitable for the 2011 onwards M3, M4, M5 and M6, it’s now possible to slide home a performance advantage to really bring the luscious power delivery of these Munich legends alive. Component sharing across the range now means the same airboxes are used so it’s possible to make the Ultimate Driving Machine even more so thanks to Induction Technology Group.
Fitting a ProFiler is a straightforward job that’s easily achievable at home using basic hand tools, these reticulated foam intake filters easily slotted into place in under 30minutes using basic hand tools, so it’s a job that almost anyone can tackle at home.
Owners of the above vehicle(s) can now benefit from ITG's decades of induction expertise, with the firm having announced the continued expansion of its ProFilter range to cater for the most diverse range of vehicles. Aside from the increase in efficiency, there are improvements with throttle response and a pleasing, yet unobtrusive increase in intake noise.
A specially created reticulated polyester foam blend optimised for high-performance applications, Tri-Foam is the material of choice for all ITG filters thanks to its multifaceted abilities. These include maximised air-flow without a corresponding drop-off in pressure, enhanced cleaning efficiency with a proven ability to trap common airborne contaminants, and impressive dust load-up tolerance. The latter ensures that ITG ProFilters can absorb a large amount of fine dust without reducing air flow capacity or efficiency. This dust load-up tolerance remains a firm reason why ITG stick with the reticulated foam construction technique, with each filter lovingly put together by hand thanks to a workforce of certified petrolheads.
The twin turbo M3 / M4 hardly needs more grunt, but hey... if there's a little bit on offer from such a small change... why not?
Tri-Foam's abilities stem from its advanced construction, with varying thicknesses of finer or coarser foams utilised for different applications. This in turn gives ITG huge flexibility and allows ITG's engineers to tailor filters to set fitments, maximising efficiency and performance. Tri-Foam filters consist of a stainless-steel wire mesh, a coarse outer-layer (designed to both prevent ingress from foreign bodies and straighten airflow), a medium grade mid-layer to trap most of the harmful dirt, and a fine inner layer, the last line of defence against minute, particle sized contaminants.
What's more, because it uses the very latest adhesive technologies to bond the foam layers, ITG filter assemblies are totally resistant to water, fumes, oils and fuels – including the exotic brews used in racing.
The Profilter's ability to filter down to a particle level is highly significant, both from a performance perspective and the continued health of BMW's huge range of lusty petrol engines.
BMW's monstrous 4.4-litre twin turbo V8 is a performance powerhouse to begin with but there's always scope for a little bit more, right?
ITG has been at the vanguard of filtration and induction technology for decades now, with a burgeoning motorsport program which sees it tasked with supplying some of the front running teams in series as diverse as F1, the BTCC and the WRC. Being involved with said championships means ITG is privy to all manner of hard-won data, the kind that's proved invaluable both when it comes to developing new fitment options and finessing existing ones. This ensures that ITG hardware doesn't merely look the part, it contributes to enhanced levels of filtration and a smooth, restriction-free induction tract, all borne from its commitment to motor racing. As a first step to making the supersaloon (and coupe) BMWs the true supercar killers they long to be, ITG is only too happy to help.
