PRP IGN-35A Ignition Coil Kit to suit Subaru EJ20 / EJ25
Everyone has been patiently waiting for the new PRP IGN-35A Ignition Coil release for the Subaru EJ20 / EJ25 platform....well wait no longer!
We’ve had these in testing in a handful of 1000+Hp 4 cyl engines for over a year now and we decided we were ready to go into full production for all of our supported engine platforms after consistent success after we ironed out the bugs with earlier generation stalks.
These monsters put out well fed over double the punch of a genuine R35 coil and are rated to 4000hp (in a 6 cylinder set up) Whilst that seems excessive but even in your 1000hp set up the results are impressive.
As we had complete control of the housing without constraints, we were able to modify primary coil configuration to make the current draw ~20% more efficient than your regular IGN1A coil pack. This allowed our 3 pin circuit to still utilise our current r35 coil harnesses we supply without requiring significant wiring upgrades, it also takes the R35 3 pin R35 connectors.
They allow for a more efficient and longer burn, as offered by the IGN1A, and since the IGN1A is the most powerful smart coil we’ve ever tested we decided to combine them as an upgrade to our extensive line of R35 coil kits.
Key Features / Kit Contains:
- The billet alloy anodized bracket is designed to securely fit all ignition coils, providing user-friendly access to both coil plugs and spark plugs without invasive modifications.
- The kit now includes custom-height, high-quality, one-piece silicone-injected spark plug stalks that seal the spark plug wells, preventing water pooling and reducing the risk of engine misfires.
- Custom-made springs are pre-fitted inside the stalks, enabling quick and easy installation without the need for trimming.
- Bench-tested, motorsport-grade branded harnesses are included, featuring high-temperature Tefzel wiring, crimp joins, OEM connectors, and glue-lined heat-shrink for enhanced durability.
- A bolt kit is included to securely mount the four ignition coils and the billet bracket to the engine head.
- Backed by a Lifetime Warranty on all PRP products

FAQs

Q: Do you ship to Quebec?
A: No — and we never will.
This decision is final and intentional.
Quebec’s tax structure and regulatory requirements create unnecessary friction for independent businesses like ours.
More importantly, the region has consistently demonstrated a lack of respect for authentic Japanese car culture, which is the foundation of everything we stand for.
The prevalence of replica parts, low-effort builds, and price-driven behavior directly contradicts our values of craftsmanship, originality, and pride.
We are not here to accommodate markets that dilute the culture.
We are not interested in adjusting our standards to fit in.
We do not respect all builds.
We respect those built with intent, effort, and pride — not for attention.
Trimotive is a brand for enthusiast, not clout chasers.
Quebec is not our market, and never will be.
Q: I’m building something custom — can Trimotive help?
A: Hell yes — that’s what we live for.
While our product line focuses on proven, platform-specific parts, we’re always excited to support builders pushing boundaries. Whether you're working on a custom swap, cross-platform setup, or a full-on Frankenstein project — we’re here for it.
We’re constantly expanding our knowledge base, and community-driven R&D is part of how we grow. If you’re doing something different, ambitious, or just plain wild — reach out. We’re always down to get involved, offer insight, and help source what you need.
If it’s built with intention, we want to be part of it.
Let’s bring that vision to life.
Q: Why doesn’t Trimotive accept returns and refunds?
A: Because we take our parts — and our partners — seriously.
Trimotive works closely with a network of specialized suppliers across North America, Japan, and beyond. Many of the products we offer are platform-specific, custom-built, or limited-production, and in many cases, made-to-order. These parts are not meant to be casually returned or resold.
Some of our suppliers are small, independent manufacturers — including one-man operations in Japan — who pour their time, skill, and pride into every product they ship. Others are high-volume performance brands with strict allocation policies. In both cases, mistakes or indecision on the buyer’s part don’t just affect us — they damage our relationships and affect everyone’s timelines.
We’re proud to work with companies that embody precision, accountability, and craftsmanship — values especially ingrained in Japanese business culture, and values that we fully adopt at Trimotive.
For this reason, we enforce a no-return policy on all non-defective items. We do not do this to be inflexible, but to protect the integrity or our supply chain and prioritize builders who plan, commit, and execute with intention.
We’re not here to accommodate indecision.
We’re here to support serious builds — and the people behind them
Q: Can I pre-order parts?
A: Yes — if you’re fully committed, we’ll make it happen.
Many of the parts we source come from small-scale manufacturers or boutique suppliers, especially in Japan, where lead times can vary significantly. Some items are made-to-order, produced in small batches, or even hand-built by single craftsmen. That’s part of the culture — and part of what makes them worth waiting for.
If you’re locked in and ready to go, we will coordinate directly with the manufacturer to confirm availability and timelines before we take your payment.
All pre-orders are paid in full and non-refundable, unless the estimated lead time becomes unreasonable or changes drastically. In those rare cases, we will issue a full refund and notify you immediately.
Pre-orders are for committed builders.
If that’s you — we’ll get you what you need.
Q: Does Trimotive offer sponsorships?
A: Yes — but only to builders who fully align with our values.
Trimotive sponsorships are reserved for individuals or teams who have a clear, standout presence in one or more of the following areas: drifting, time attack, drag racing, or functional show builds. We’re not interested in social media clout — we’re interested in execution, discipline, and authenticity.
We only consider cars that:
Are built with purpose, not just for photos
Use proven, high-quality parts only (no replicas, no shortcuts)
Represent a genuine commitment to the culture, not just the spotlight
If your project stands out and reflects the level of devotion we expect, reach out with a full build sheet, current photos, and a clear statement of your goals. If we see alignment — we’ll talk.
