What is the difference between the HKS Hi-Power and HKS Legamax exhaust?

Hi-Power: loud and aggressive, for track and enthusiast use. Legamax: quieter, designed for everyday road use — still lighter than OEM with a sporty tone. For daily driving the Legamax is the more practical choice.

Which HKS spark plug fits my Toyota GR86 or GT86?

GT86 (FA20): Super Fire Racing M45iL (50003-M45iL). GR86 (FA24): Super Fire Racing MR45XLZ (50003-MR45XLZ). The GR86 requires a longer plug due to its larger displacement.

Do I have to pay customs duties when ordering from Streetstylez?

No. Streetstylez handles all customs clearance in Germany. Fixed euro price including VAT, no additional costs for EU customers.

I can't find the HKS part I'm looking for — can you source it?

In most cases yes. Send the part name or HKS part number via WhatsApp or email. We usually respond within one business day.

What is the HKS Hipermax S and who is it for?

The Hipermax S is HKS' flagship street coilover with Dual PVS technology. Ideal for cars driven on both road and track — excellent balance of comfort and performance.

Frequently Asked Questions about HKS

The Hi-Power is HKS' classic performance exhaust — loud, aggressive and designed for track and enthusiast use. The Legamax is built for everyday road use: noticeably quieter than the Hi-Power, but still lighter than the factory system with a sporty tone. For daily driving on public roads, the Legamax is the more practical choice.

The GT2 Supercharger Kit does not have a general type approval (ABE) and requires individual road approval under German §21 StVZO. This means the kit can be assessed by an approved vehicle inspector (TÜV, DEKRA or GTÜ), but it is not a simple plug-and-play installation from a legal standpoint. We recommend contacting an approved testing centre before purchasing.

For the GT86 with FA20 engine and GR86 with FA24, HKS recommends the Super Fire Racing M45HL (part no. 50003-M45HL).

No. We import all HKS products directly to Germany and handle all customs clearance. You purchase from a registered German company and pay the listed euro price including VAT — no additional costs, no surprises. This applies to all deliveries within the EU.

In most cases, yes. HKS has over 10,000 products in their catalogue — not everything is listed in the shop. Send us the exact part name or HKS part number via WhatsApp or email and we'll check availability and price. We usually get back to you within one business day.

HKS (Hasegawa Kikaku Seisakusho) was founded in 1973 in Fujinomiya, Japan and is one of the world's most recognised performance tuning manufacturers. The product range includes exhaust systems (Hi-Power, Legamax, Hi-Power Spec L), coilovers (Hipermax S, Hipermax IV, Hipermax R), supercharger kits (GT2 for GR86, BRZ, S2000), intake systems, turbochargers and spark plugs (Super Fire Racing M-Series).
