Common Applications

The 326POWER 3D☆STAR Alphard Side Under Spoiler is designed as a lower side styling upgrade for Toyota AGH/GGH3# Alphard Late Model vehicles equipped with the Aero Grade body configuration.

It is suitable for customers who want to visually lower and extend the side profile without replacing the complete factory side bodywork.

The relatively simple shape works particularly well on Alphard builds where the front and rear aero components are intended to provide the stronger styling accents.

The Side Under Spoiler can be installed individually or combined with the matching 3D☆STAR Front Under Spoiler and Rear Under Spoiler for a coordinated F/S/R exterior setup.

Final compatibility depends on vehicle specification, factory Aero Grade configuration, side body condition, mounting area, alignment, and installation method.

326POWER Character

326POWER is known for distinctive Japanese tuning style, lowered vehicles, aggressive fitment, stance culture, and aero products with a strong visual identity.

For the Alphard, however, the 3D☆STAR design takes a more mature and luxury-focused approach.

The official concept combines the large, premium body of the Alphard with a European-inspired styling direction. The aero components attach to the lower portion of the factory Aero Grade bodywork, visually emphasizing a lower stance while retaining the recognizable character of the original vehicle.

3D☆STAR Alphard Side Design Notes

Unlike the more visually complex front and rear sections, the Side Under Spoiler was intentionally designed to remain simple.

326POWER describes the side section as a flat board extending from the front toward the rear with an outward projection of approximately 20 mm.

This consistent projection creates a clean lower line along the side of the Alphard.

The design philosophy is deliberate: by keeping the side section restrained, the stronger styling features of the front and rear aero components become more noticeable.

This helps maintain overall balance across the vehicle rather than making every section overly complex.

20 mm Flat-Board Design

A defining feature of this product is the approximately 20 mm outward projection running from the front to the rear of the Side Under Spoiler.

Instead of varying dramatically along its length, the spoiler maintains a flat-board style profile.

This gives the vehicle a cleaner and more consistent side appearance and helps visually extend the lower body line.

The result is subtle compared with the front and rear pieces, but that simplicity is intentional within the complete 3D☆STAR Alphard design.

Paint Separation Notes

The official Alphard design concept was developed with contrasting paint finishes in mind.

326POWER specifically notes that different paint colors are effective on the Side Under Spoiler as well.

Paint separation can be used to emphasize the flat-board design and visually distinguish the aero component from the factory bodywork.

Customers can choose to match the body color for a more integrated appearance or use a contrasting finish to make the lower side section more noticeable.

Final paint layout and color selection are up to the customer and body shop.

Installation and Fitment Notes

This Side Under Spoiler is designed for Toyota AGH/GGH3# Alphard Late Model vehicles with the Aero Grade body configuration.

Before painting, the product must be test fitted to the actual vehicle.

The official instructions require test fitting, alignment adjustment, and fitment checking before painting. If mounting-hole locations are difficult to align, gradual adjustment such as elongated-hole processing may be required.

Depending on the individual vehicle and installation condition, additional drilling, trimming, sanding, mounting adjustment, or other preparation work may also be necessary.

Customers should check:

Factory side body alignment
Lower side mounting position
Front-to-rear spoiler alignment
Door clearance
Ground clearance
Mounting-hole positions
Panel fitment
Overall left and right positioning

Professional installation and body-shop preparation are strongly recommended.

Aero Product Notes

The product is supplied unpainted in a white gel coat finish. Installation and painting are not included.

Aero molded products normally require surface preparation before final painting and installation.

Minor surface irregularities such as pinholes, uneven areas, mold-release marks, or other small molding imperfections may require correction during normal sanding and body-shop preparation.

The Side Under Spoiler should be completely test fitted and aligned before paintwork begins.

Because the component sits along the lower side of the vehicle, final ground clearance should also be checked carefully, particularly on lowered Alphard builds.
