This kit covers your whole engine bay
One configured kit, built from our individual carbon fiber pieces. Each piece is also sold on its own, linked below.
- Radiator cooling shroud
- Engine cover, in OEM, MP or EVE with MP Strip style
- ECU and battery terminal cover
- Engine bay corner covers, pair
- Headlight cover panels, pair
- Strut bar, your choice of Tri-Color, V-Shape or CSL
- Air intake covers, pair, included unless you opt out
- A V2 titanium bolt set in your choice of color, a limited-time gift with this kit
Most carbon engine bay kits stop at the covers and sell the strut brace on its own. This one includes it, configured and priced as a single kit.
Choosing your options
Engine Cover. OEM Style is the factory profile in carbon. MP Style is the M Performance look at a fraction of its cost. EVE with MP Strip is an aggressive vented design with deep cooling scoops and the M tricolor strip.
Strut Bar. Tri-Color has anodized CNC end brackets in red, blue and black. V-Shape is the front and rear brace, shaped to clear the air intake covers. CSL is the CSL-style open brace in carbon, where BMW's own CSL brace is heavy cast aluminum.
Air Intake Covers. Included, or Not Included. The CSL brace occupies the intake cover space, so the two cannot be fitted together, and owners on an aftermarket intake do not need them.
At checkout, with no change in price, you tell us your finish (Gloss or Matte), drive side, your headlight panels (by model, or the Alpha-N option if you run that cover), your bolt color, and the bracket color if you chose CSL.
What is in the kit
Every kit includes the radiator cooling shroud, your chosen engine cover, the ECU and battery terminal cover, the corner covers as a pair, the headlight panels as a pair, and your chosen strut bar. The air intake covers are added unless you opt out or run the CSL strut. A V2 titanium bolt set is included as a limited-time gift with this kit, in your choice of color.
Construction
Pre-preg dry carbon fiber, autoclave cured, also known as dry carbon. The weave is laid for a tight, consistent pattern with far fewer surface pinholes than hand laid wet carbon, filled at the sealer stage. Each piece carries a 2K clear coat with UV absorbers and a heat resistant outer layer.
Finish and Full Thermal Clear Coat
Gloss or Matte at the same price. For the longest lived finish in a hot engine bay, our Full Thermal Clear Coat runs the heat resistant system through every layer rather than the outer one alone. It is available on the individual pieces, or contact us to spec the whole kit in Full Thermal. Read how it works.
Headlight panels and the Alpha-N engine cover
The M2 and the M3 and M4 use different headlight panels, so pick your model at checkout. If you run an aftermarket Alpha-N engine cover, it clashes with the standard panels, so choose the Alpha-N option for your model and we fit the matching set at no extra cost.
Fitment
BMW G80 M3 (2021 and up), G82 M4 (2021 and up), G87 M2 (2023 and up). S58 engine.
Install
Each piece mounts to factory points. The engine cover sits beneath the strut bar, so the bar is fitted last. A full bay is a larger job than a single piece, and many owners have it fitted by a trim or performance shop. Fully reversible.

Engineered to fit from day one
Built from OEM geometry and on-car scans, refined through multiple prototype corrections, then produced with metal tooling and jigs that control mounting-hole positions, edges and curvature. Each batch undergoes dimensional sampling so parts leave the line aligned to factory contours—reducing install effort and eliminating product-caused fitment issues.
Finish standards: flatness first
Many can get the structure right; few invest to make the surface look truly premium. We spend on interlayer leveling, fine sanding, multi-coat clear coat and controlled curing: straight reflections under strong light, crisp weave definition, and long-term resistance to UV yellowing, hazing and cracking. That’s the visible difference.
Delivery & support: fast and worry-free
A specialist replies within 24 hours on weekdays. Every piece is dispatched after final inspection (QC) and reinforced packing, with end-to-end tracking; lead time varies by item and finish and is confirmed after purchase. Before dispatch, every unit receives a final inspection—jig-based mounting-hole/fit checks and bright-light surface review—to catch issues before they travel. If installation proves tricky, our engineering and support teams will assist, and any shipping issues are prioritized. Faster handoff and dependable service save you time and friction.
Make every exit an entrance
Upgrade with Confidence
Precision in Every Layer
Every part ships with our standard finish: the weave filled and leveled by hand, then disciplined coats of UV-stable clear laid to a real thickness, already at or past the best on the market. For the large exterior panels, an optional Concours finish goes further, built up and leveled to a mirror depth meant to rival anything on a supercar. It is slow, costly, and built only on request. Standard or Concours, every piece carries the same obsession with fit, finish, and how it lasts.
FAQs
Please read our FAQs page to find out more.
Will this fit my exact model, trim, and year (LCI/Pre-LCI, M Sport vs. base)?
Yes—fitment follows OEM geometry. At checkout we require your vehicle details (model/year, trim, LCI/Pre-LCI, bumper type/photos) and perform a second verification. If your selection doesn’t match your vehicle, we’ll alert you before fulfillment to correct it.
What if I have aftermarket bumpers or prior bodywork?
Aftermarket bumpers and vehicles with prior collisions or repairs (even minor scrapes) can alter mounting geometry, which may cause installation difficulty. We’ve seen cases where a previous accident left the bumper deformed, making parts hard to seat—this is not a product defect. Please have your installer inspect mounting points before ordering.
Do I need to drill or cut?
Dry carbon: installs via factory mounting points; no drilling is generally required, except some rear wings that may require trunk drilling.
Wet carbon: due to process characteristics and possible deformation during transit or humidity changes, self-tapping screws may be needed to secure fitment.
Will the carbon tone match if I replace a single piece later?
Single-piece replacements are available. Minor batch-to-batch tone variance is normal; for perfect symmetry on L/R paired parts, replacing as a set is recommended. If you purchased from us and later damaged a part in a collision, send photos— we can usually offer a returning-customer discount on the replacement.
Will sensors, radar, PDC, and tow-hook access still work?
Some carbon grilles include pre-cut radar/PDC windows. Please review product photos carefully or provide OEM front-end photos before ordering. We typically re-confirm before shipment. If a misread leads to the wrong variant being ordered, exchanges are possible, but additional shipping costs may apply.
Can I choose gloss vs. matte or request specific finish options?
Standard is our multi-layer, UV-stable gloss clear. Matte and special finishes can be built to order; lead time will differ.
What’s included in the box? Will I need extra hardware or tape?
Each product page lists what’s included. Vehicle-specific clips/brackets are included when required; high-bond tape or fasteners are provided where applicable. If an item needs OE hardware reuse, we’ll state it clearly.
What happens if my item arrives damaged?
You’re covered. Contact us within 48 hours with photos of the outer box, inner packaging, labels, and the part. We’ll arrange a replacement or a fair resolution at no extra cost. Keep the packaging until we confirm next steps.
What payment methods do you accept? Is it secure?
We accept major credit and debit cards (Visa, Mastercard, American Express and more) through Shopify Payments, plus Shop Pay, Apple Pay, Google Pay and PayPal. All payments settle in USD through secure, PCI-compliant gateways with industry-standard encryption and fraud screening.
